Subject: SI-6565 Adds missing flag values to reflection API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Among the flags requested by our users, the most popular are definitely
PARAMACCESSOR and CASEACCESSOR. Among other things that are missing in
2.10.x are SYNTHETIC and its close friend ARTIFACT. Apparently, SYNTHETIC
was was added somewhen during the 2.11.0-M* development cycle, so I only
has to introduce ARTIFACT.

There was also METHOD as requested by Paul in https://github.com/xeno-by/declosurify/blob/ce6c55b04086c755102227dd8124b0bf0dac46e1/src/main/scala/macros.scala#L102,
but the absence of that one is compensated by the fact that it’s only needed
when manually creating symbols, and for that we already have Symbol.newMethodSymbol.

This doesn't remove the necessity to see SI-6267 through (read the recently
updated issue description for more information!), but that'd be a significant
change, so let's delay it until better times.

Subject: SI-7533 Adds Symbol.isAbstract

Amazingly enough, we've missed the fact that non-type symbols can also
be abstract. Having been enlightened by this, I'm exposing isDeferred
and merging it along with isAbstractType and isAbstractClass into the
unified Symbol.isAbstract method.

Subject: SI-6733 LOCAL, isLocal, and private[this]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Due to an unfortunate name collision, internal.Symbols#Symbol.isLocal
means something different from Flag.LOCAL. Therefore api.Symbols#Symbol.isLocal
was directly violating its documentation.

Since we can’t give api#isLocal an implementation different from internal#isLocal,
we have to rename, and for that occasion I have come up with names
api#isPrivateThis and api#isProtectedThis, which in my opinion suits the
public API better than internal#isPrivateLocal and internal#isProtectedLocal.

Given the extraordinary circumstances of having no way for api#isLocal
to work correctly, I’m forced to remove api#isLocal without a deprecation
notice, exercising our right to break experimental APIs, something that
we have never done before for reflection or macros. This is sad.

Subject: disambiguates uses of “local” in internal symbol API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There’s been a conflation of two distinct meanings of the word “local”
in the internal symbol API: the first meaning being “local to this”
(as in has the LOCAL flag set), the second meaning being “local to block”
(as in declared in a block, i.e. having owner being a term symbol).

Especially confusing is the fact that sym.isLocal isn’t the same as
sym.hasFlag(LOCAL), which has led to now fixed SI-6733.

This commit fixes the semantic mess by deprecating both Symbol.isLocal and
Symbol.hasLocalFlag (that we were forced to use, because Symbol.isLocal
had already been taken), and replacing them with Symbol.isLocalToThis
and Symbol.isLocalToBlock. Unfortunately, we can’t remove the deprecated
methods right away, because they are used in SBT, so I had to take small
steps.

Subject: SI-8187 api#Symbol.name now has precise type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I don’t remember why we didn’t have written it as `def name: NameType`
in the first place (probably because of path-dependent bugs that were
popping up every now and then when we were developing the first version
of reflection API), but now there are definitely no obstacles to that.

Subject: SI-8190 erasure identities for types in reflection API

Makes sure that almost every abstract type declared in reflection API
erases to a unique class, so that they can be adequately used for
method overloading to the same extent that tags allow them to be used
in pattern matching.

The only two exceptions from this rule are the types whose implementations
we do not control: FlagSet that is implemented as Long and RuntimeClass
that is implemented as java.lang.Class[_].

Subject: additional class tags for reflection API

Introduces a test that iterates all abstract types in reflection API
and makes sure that every one of them has an associated class tag.

After being introduced, the test has immediately failed exposing
the lack of tags for TreeCopier, Mirror and RuntimeClass, which has been
subsequently fixed in this commit.

Subject: SI-6379 adds MethodSymbol.exception
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Following Simon’s request, this commit introduces a dedicated API
that can be used to acquire the list of exceptions thrown by a method,
abstracting away from whether it’s a Java or a Scala artifact.

Exposes a popular code pattern in macros as a dedicated reflection API.
This simple commit, however, ended up being not so simple, as it often
happens with our compiler.

When writing a test for the new API, I realized that our (pre-existing)
MethodSymbol.isPrimaryConstructor API returns nonsensical results for
implementation artifacts (trait mixin ctors, module class ctors).

What’s even more funny is that according to our reflection internals,
even Java classes have primary constructors. Well, that’s not surprising,
because `primaryConstructor` is just `decl(ctorName).alternatives.head`.
Good thing that package classes don’t have constructors or that would
elevate the situation to three fries short of a happy meal.

At the moment, I’m too scared to fiddle with internal#Symbol.primaryConstructor,
because that could easily break someone right before RC1, so I simply
documented the findings in SI-8193 and postponed the actual work, except
for one thing - isJavaDefined symbols no longer have primary constructors.

Subject: SI-6484 adds Universe.typeOf[T](x: T)

This is a nice addition to Universe.typeOf[T], quite frequently useful
for inspecting ad-hoc types.

As promised by https://github.com/scala/scala/pull/1741, which represented
my previous stab at adding this API, I ran into problems when trying to
introduce the API naively.

  def typeOf[T](implicit ttag: TypeTag[T]): Type
  def typeOf[T: TypeTag](x: T): Type

The first problem came from the fact that even though they don't look
ambiguous, under certain circumstances, the couple of typeOf overloads
can become ambiguous. Concretely, ambiguity happens when T <: TypeTag[T],
which makes the compiler uncapable to choose an overload to typecheck
`typeOf[T](<materialized>: TypeTag[T])`. Luckily, defining x as a by-name
parameter fixes the problem.

  def typeOf[T](implicit ttag: TypeTag[T]): Type
  def typeOf[T: TypeTag](x: => T): Type

The second problem manifested itself in reification of snippets that
contained calls to typeOf. Apparently, materialized tags get rolled back
by reify as products of macro expansion, becoming replaced with
`implicitly[TypeTag[T]]`. Afterwards, subsequent rollback of TypeTree's
strips the replacement of its type argument, producing bare `implicitly`.
Back then when typeOf wasn't overloaded, this abomination typechecked
and worked correctly, but now, due to some weird reason, it stopped.
I have worked around this by performing the rollback on a larger scale -
instead of hunting down materialized tags, this commit detects calls
to typeOf and removes their implicit argument lists altogether.

Subject: SI-8194 adds Universe.symbolOf[T]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A very frequent use for a result of typeOf is obtaining an underlying
type symbol. Another thing that comes up occasionally at stack overflow
is a request to add facilities for reification of symbols.

This naturally suggests that our reflection API would benefit from a method
called symbolOf that can take a term or type argument and return an underlying
symbol.

While an API to extract a term symbol from an expression needs some time
to be designed and then implemented robustly (we don’t have untyped macros
so we’ll have to account for various desugarings), meaning that we probably
won’t have time for that in 2.11, a type symbol extractor seems to be
a very low-hanging fruit.

Subject: adds showDeclaration(sym: Symbol): String
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per Paul’s request, this commit exposes Symbol.defString, although
in a different way to ensure consistency with our other prettyprinting
facilities provided in the reflection API.

normalize is a highly overloaded name and it also conflates two distinct

It’s very probable that this is the single most requested method in the

Subject: SI-8063 exposes much needed conveniences for Type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per Jason’s request, Type now features such important convenience
methods as typeArgs, typeParams, paramss, resultType and finalResultType
without requiring to perform any casts.

Subject: adds Type.companionType

Introduces a dedicated facility to go from a type to a type of its companion.
Previously we had to do something really horrible for that, something like:
tp.typeSymbol.companionSymbol.typeSignature.

Subject: sane semantics for Symbols.companionSymbol
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While playing with tests for Type.companionType, I figured out that
companionSymbol isn’t what it seems to be:

scala> ScalaPackage.companionSymbol
res5: $r.intp.global.Symbol = <none>

scala> ScalaPackageClass.companionSymbol
res6: $r.intp.global.Symbol = package scala

Or even funnier observation:

scala> class C; object C
defined class C
defined object C

scala> val classC = typeOf[C].typeSymbol
classC: $r.intp.global.Symbol = class C

scala> val moduleC = classC.companionSymbol
moduleC: $r.intp.global.Symbol = object C

scala> classC.companionSymbol == moduleC
res0: Boolean = true

scala> moduleC.companionSymbol == classC
res1: Boolean = true

scala> moduleC.moduleClass.companionSymbol == moduleC
res2: Boolean = true

Of course, I rushed to clean this up, so that `companionSymbol` only
returns something other than NoSymbol if the target has a companion in
the common sense, not wrt the internal “class with the same name in the
same package” convention of scalac, and that `companionSymbol` for
module classes is a class, not a source module.

Unfortunately it’s not that easy, because api.Symbol#companionSymbol
has the same name as internal.Symbol#companionSymbol, so we can’t change
the behavior of the former without changing the behavior of the latter.

Therefore I deprecated api.Symbol#companionSymbol and introduced a replacement
called api.Symbol#companion with sane semantics.

Subject: ValOrDefDef.name is now TermName
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Back then when we planned to introduce type macros, we relaxed the type
of DefDef.name from TermName to Name in order to potentially be able to
accommodate type names for type macros.

Since then, type macros have been cancelled (and, for the record, my
implementation of type macros in paradise 1.0 didn’t involve DefDefs
with TypeNames), and we’ve rolled back the change to DefDef.name.

What we forgot to do, however, was to change the type of ValOrDefDef.name,
which is taken care of in this commit.

Subject: SI-8118 simplifies Annotation down to a plain Tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per https://groups.google.com/forum/#!topic/scala-internals/8v2UL-LR9yY,
annotations don’t have to be represented as AnnotationInfos and can be
reduced to plain Trees.

Due to compatibility reasons and because of the limitations of the cake
pattern used in implementing current version of Reflection, we can’t
just say `type Annotation = Tree`, however what we can definitely do is
to deprecate all the methods on Annotation and expose `tree: Tree` instead.

- *  both `scalaArgs` and `javaArgs`. For Scala or Java annotations extending [[scala.annotation.ClassfileAnnotation]] `scalaArgs` is empty
- *  and arguments are stored in `javaArgs`. For all other Scala annotations, arguments are stored in `scalaArgs` and `javaArgs` is empty.
+ *  Both Java and Scala annotations are represented as typed trees carrying constructor invocations corresponding
+ *  to the annotation. For instance, the annotation in `@ann(1, 2) class C` is represented as `q"@new ann(1, 2)"`.
  *
- *  Arguments in `scalaArgs` are represented as typed trees. Note that these trees are not transformed by any phases
- *  following the type-checker. Arguments in `javaArgs` are repesented as a map from [[scala.reflect.api.Names#Name]] to
- *  [[scala.reflect.api.Annotations#JavaArgument]]. Instances of `JavaArgument` represent different kinds of Java annotation arguments:
- *    - literals (primitive and string constants),
- *    - arrays and
- *    - nested annotations.
+ *  Unlike Java reflection, Scala reflection does not support evaluation of constructor invocations stored in annotations
+ *  into underlying objects. For instance it's impossible to go from `@ann(1, 2) class C` to `ann(1, 2)`, so one
+ *  has to analyze trees representing annotation arguments to manually extract corresponding values. Towards that end,
+ *  arguments of an annotation can be obtained via `annotation.tree.children.tail`.
  *
  *  For more information about `Annotation`s, see the [[http://docs.scala-lang.org/overviews/reflection/annotations-names-scopes.html Reflection Guide: Annotations, Names, Scopes, and More]]

As per multiple user requests, this commit introduces a shortcut
to typecheck trees under multiple different modes: terms (EXPRmode,
was exposed in Scala 2.10) and types (TYPEmode).

Looking into the rest of a dozen of internal typechecker modes, to the
best of my knowledge, I can’t find other modes that we could expose.
FUNmode is useful, but very situational. PATTERNmode is useful, but
also situational, because we don’t expand macros inside patterns
except for whitebox extractor macros. The rest (e.g. POLYmode or TAPPmode)
are too low-level.

Subject: SI-6931 cleans up the position API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I have finally overcome my fear of positions and got to cleaning up its
public interface.

Apparently it isn’t so bad, since there’s a sane core of methods (thanks
to whoever wrote the comments to internal#Position):
  1) Checks to distinguish offsets, opaque ranges and transparent ranges
  2) Essentials that inclide start, point, end and source
  3) Factories that create new positions based on existing ones

It looks like methods from the 3rd group are exactly what we’ve been looking
for in SI-6931, so we have nothing to add in this commit.

+ *  issuing an error message, usually a Name. A range position can be designated

+ *  Note: some of these invariants actually apply to the trees which carry
+ *  the positions, but they are phrased as if the positions themselves were
+ *  the parent/children for conciseness.
+ *
+ *  Invariant 1: in a focused/offset position, start == point == end
+ *  Invariant 2: in a range position,          start <= point <  end
+ *  Invariant 3: an offset position never has a child with a range position
+ *  Invariant 4: every range position child of a range position parent is contained within its parent
+ *  Invariant 5: opaque range position siblings overlap at most at a single point
+ *
+ *  The following tests are useful on positions:
+ *
+ *  pos.isDefined     true if position is not an UndefinedPosition (those being NoPosition and FakePos)
+ *  pos.isRange       true if position is a range (opaque or transparent) which implies start < end
+ *  pos.isOpaqueRange true if position is an opaque range
+ *
+ *  The following accessor methods are provided - an exception will be thrown if
+ *  point/start/end are attempted on an UndefinedPosition.
+ *
+ *  pos.source       The source file of the position, or NoSourceFile if unavailable
+ *  pos.point        The offset of the point
+ *  pos.start        The (inclusive) start offset, or the point of an offset position
+ *  pos.end          The (exclusive) end offset, or the point of an offset position
+ *
+ *  The following conversion methods are often used:
+ *
+ *  pos.focus           Converts a range position to an offset position focused on the point
+ *  pos.makeTransparent Convert an opaque range into a transparent range

Subject: SI-8086 addresses problem with calling Symbol.getter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Due to an unintended clash between `def getter: Symbol` (public reflection)
and `def getter(base: Symbol): Symbol` (internal reflection), the former
is uncallable from compiler internals and/or REPL’s power mode.

While both methods are guarded by compatibility constraints, we can’t
solve this problem radically and will have to live with it for some time
Thankfully, a replacement for `sym.getter` is quite approachable, namely:
`sym.getter(sym.owner)`.

In the meanwhile, I’ve deprecated the internal `getter` method by
renaming it to `getterIn`, also touching a nearby `superSymbol`. In the next
release we’ll be able to fix the name clash for good.

Subject: SI-6441 removes Symbol.isOverride
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`Symbol.isOverride` joins `Symbol.isLocal` in the unfortunate family
of methods for which we had to break source compatibility because of
their utter brokenness.

Apparently, `isOverride` only returns true for those symbols that have
the OVERRIDE flag set (i.e. the ones that are derived from source definitions
that have the `override` modifier specified next to them). Of course,
this is very confusing, and that’s exacerbated by the fact that we can’t
fix this behavior, because there’s `internal#Symbol.isOverride` that someone
might rely on.

Given that there’s perfectly working `Symbol.allOverriddenSymbols`,
this commit removes the `Symbol.isOverride` API altogether.

Subject: SI-6732 deprecates internal#Symbol.isPackage

This is the first step in disentangling api#Symbol.isPackage, which is
supposed to return false for package classes, and internal#Symbol.isPackage,
which has traditionally being used as a synonym for hasPackageFlag and
hence returned true for package classes (unlike isModule which is false
for module classes).

Subject: deprecates String => Name implicit conversions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Given that in 2.11 we have upgraded our name construction facility
from `newTxxxName` to `TxxxName`, I think it’s time we retire these
implicit conversions, as they no longer save keystrokes, but continue
to present ambient danger associated with implicit conversions.

Subject: deprecates api#Name.decoded and api#Name.encoded
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Presence of both decoded/encoded and decodedName/encodedName has always
baffled me, as one of those method groups is clearly redundant, and
this pull request presents a great opportunity to address this by
deprecating one of the groups.

After some deliberation, I’ve chosen decoded/encoded as the deprecation
target, because its derivation from decodedName/encodedName is easier
than the other way around.

Subject: establishes scala.reflect.api#internal

Reflection API exhibits a tension inherent to experimental things:
on the one hand we want it to grow into a beautiful and robust API,
but on the other hand we have to deal with immaturity of underlying mechanisms
by providing not very pretty solutions to enable important use cases.

In Scala 2.10, which was our first stab at reflection API, we didn't
have a systematic approach to dealing with this tension, sometimes exposing
too much of internals (e.g. Symbol.deSkolemize) and sometimes exposing
too little (e.g. there's still no facility to change owners, to do typing
transformations, etc). This resulted in certain confusion with some internal
APIs living among public ones, scaring the newcomers, and some internal APIs
only available via casting, which requires intimate knowledge of the
compiler and breaks compatibility guarantees.

This led to creation of the `internal` API module for the reflection API,
which provides advanced APIs necessary for macros that push boundaries
of the state of the art, clearly demarcating them from the more or less
straightforward rest and providing compatibility guarantees on par with
the rest of the reflection API.

This commit does break source compatibility with reflection API in 2.10,
but the next commit is going to introduce a strategy of dealing with that.

-/**
- * <span class="badge badge-red" style="float: right;">EXPERIMENTAL</span>
- *
- * This trait provides support for importers, a facility to migrate reflection artifacts between universes.
- * ''Note: this trait should typically be used only rarely.''
- *
- *  Reflection artifacts, such as [[scala.reflect.api.Symbols Symbols]] and [[scala.reflect.api.Types Types]],
- *  are contained in [[scala.reflect.api.Universe Universe]]s. Typically all processing happens
- *  within a single `Universe` (e.g. a compile-time macro `Universe` or a runtime reflection `Universe`), but sometimes
- *  there is a need to migrate artifacts from one `Universe` to another. For example, runtime compilation works by
- *  importing runtime reflection trees into a runtime compiler universe, compiling the importees and exporting the
- *  result back.
- *
- *  Reflection artifacts are firmly grounded in their `Universe`s, which is reflected by the fact that types of artifacts
- *  from different universes are not compatible. By using `Importer`s, however, they be imported from one universe
- *  into another. For example, to import `foo.bar.Baz` from the source `Universe` to the target `Universe`,
- *  an importer will first check whether the entire owner chain exists in the target `Universe`.
- *  If it does, then nothing else will be done. Otherwise, the importer will recreate the entire owner chain
- *  and will import the corresponding type signatures into the target `Universe`.
- *
- *  Since importers match `Symbol` tables of the source and the target `Universe`s using plain string names,
- *  it is programmer's responsibility to make sure that imports don't distort semantics, e.g., that
- *  `foo.bar.Baz` in the source `Universe` means the same that `foo.bar.Baz` does in the target `Universe`.
- *
- *  === Example ===
- *
- *  Here's how one might implement a macro that performs compile-time evaluation of its argument
- *  by using a runtime compiler to compile and evaluate a tree that belongs to a compile-time compiler:
- *
- *  {{{
- *  def staticEval[T](x: T) = macro staticEval[T]
- *
- *  def staticEval[T](c: scala.reflect.macros.blackbox.Context)(x: c.Expr[T]) = {
- *    // creates a runtime reflection universe to host runtime compilation
- *    import scala.reflect.runtime.{universe => ru}
- *    val mirror = ru.runtimeMirror(c.libraryClassLoader)
- *    import scala.tools.reflect.ToolBox
- *    val toolBox = mirror.mkToolBox()
- *
- *    // runtime reflection universe and compile-time macro universe are different
- *    // therefore an importer is needed to bridge them
- *    // currently mkImporter requires a cast to correctly assign the path-dependent types
- *    val importer0 = ru.mkImporter(c.universe)
- *    val importer = importer0.asInstanceOf[ru.Importer { val from: c.universe.type }]
- *
- *    // the created importer is used to turn a compiler tree into a runtime compiler tree
- *    // both compilers use the same classpath, so semantics remains intact
- *    val imported = importer.importTree(tree)
- *
- *    // after the tree is imported, it can be evaluated as usual
- *    val tree = toolBox.untypecheck(imported.duplicate)
- *    val valueOfX = toolBox.eval(imported).asInstanceOf[T]
- *    ...
- *  }
- *  }}}

+   *  by providing not very pretty solutions to enable important use cases.
+   *
+   *  In Scala 2.10, which was our first stab at reflection API, we didn't have a systematic
+   *  approach to dealing with this tension, sometimes exposing too much of internals (e.g. Symbol.deSkolemize)
+   *  and sometimes exposing too little (e.g. there's still no facility to change owners, to do typing
+   *  transformations, etc). This resulted in certain confusion with some internal APIs
+   *  living among public ones, scaring the newcomers, and some internal APIs only available via casting,
+   *  which requires intimate knowledge of the compiler and breaks compatibility guarantees.
+   *
+   *  This led to creation of the `internal` API module for the reflection API, which

+   *  are contained in [[scala.reflect.api.Universe Universe]]s. Typically all processing happens
+   *  within a single `Universe` (e.g. a compile-time macro `Universe` or a runtime reflection `Universe`), but sometimes
+   *  there is a need to migrate artifacts from one `Universe` to another. For example, runtime compilation works by
+   *  importing runtime reflection trees into a runtime compiler universe, compiling the importees and exporting the
+   *  result back.
+   *
+   *  Reflection artifacts are firmly grounded in their `Universe`s, which is reflected by the fact that types of artifacts
+   *  from different universes are not compatible. By using `Importer`s, however, they be imported from one universe
+   *  into another. For example, to import `foo.bar.Baz` from the source `Universe` to the target `Universe`,
+   *  an importer will first check whether the entire owner chain exists in the target `Universe`.
+   *  If it does, then nothing else will be done. Otherwise, the importer will recreate the entire owner chain
+   *  and will import the corresponding type signatures into the target `Universe`.
+   *
+   *  Since importers match `Symbol` tables of the source and the target `Universe`s using plain string names,
+   *  it is programmer's responsibility to make sure that imports don't distort semantics, e.g., that
+   *  `foo.bar.Baz` in the source `Universe` means the same that `foo.bar.Baz` does in the target `Universe`.
+   *
+   *  === Example ===
+   *
+   *  Here's how one might implement a macro that performs compile-time evaluation of its argument
+   *  by using a runtime compiler to compile and evaluate a tree that belongs to a compile-time compiler:
+   *
+   *  {{{
+   *  def staticEval[T](x: T) = macro staticEval[T]
+   *
+   *  def staticEval[T](c: scala.reflect.macros.blackbox.Context)(x: c.Expr[T]) = {
+   *    // creates a runtime reflection universe to host runtime compilation
+   *    import scala.reflect.runtime.{universe => ru}
+   *    val mirror = ru.runtimeMirror(c.libraryClassLoader)
+   *    import scala.tools.reflect.ToolBox
+   *    val toolBox = mirror.mkToolBox()
+   *
+   *    // runtime reflection universe and compile-time macro universe are different
+   *    // therefore an importer is needed to bridge them
+   *    // currently mkImporter requires a cast to correctly assign the path-dependent types
+   *    val importer0 = ru.internal.mkImporter(c.universe)
+   *    val importer = importer0.asInstanceOf[ru.internal.Importer { val from: c.universe.type }]
+   *
+   *    // the created importer is used to turn a compiler tree into a runtime compiler tree
+   *    // both compilers use the same classpath, so semantics remains intact
+   *    val imported = importer.importTree(tree)
+   *
+   *    // after the tree is imported, it can be evaluated as usual
+   *    val tree = toolBox.untypecheck(imported.duplicate)
+   *    val valueOfX = toolBox.eval(imported).asInstanceOf[T]
+   *    ...
+   *  }

From 2155ca4bba9de396bde32588e63736042178ca49 Mon Sep 17 00:00:00 2001

Subject: reflection API compatibility with 2.10.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is just one of the possible strategies for compatibility with
reflection API of 2.10.x family. Here’s the discussion:

1) Do nothing.

Document the fact that we’ve organized internal APIs in a separate module
and let people figure out themselves.

Pros: no boilerplate on our side.
Cons: potential for confusion, major upfront migration effort.

2) (This commit). Introduce a compatibility pack with a manual import.
Compatibility pack lives in a separate module that has to be manually imported.
People will get compilation errors when trying to compile macros using
internal APIs against 2.11, but those will be quenched by a single
`import compat._` import. Compatibility stubs would still produce
deprecation warnings, but people can choose to ignore them to alleviate
migration costs.

Pros: brings attention of the users to the fact that they are using
internal APIs by providing a more powerful nudge than just deprecation.
Cons: even though migration effort is trivial, it is still non-zero.

3) Deprecate internal APIs in-place.

Pros: zero migration effort required.
Cons: those who ignore deprecations will be unaware about using internal APIs,
there will be some naming conflicts between Universe.xxxType and internal.xxxType
type factories.

Subject: adds initialize and fullyInitialize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per Paul’s request, this commit introduces facilities to force initialization
of reflection artifacts.

Sure, initialize (actually, even fullyInitialize) is silently performed
by Symbol.typeSignature for runtime reflection, but people don’t have to
know about that.

Subject: adds Context.enclosingOwner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per discussion at https://groups.google.com/forum/#!topic/scala-internals/nf_ooEBn6-k,
this commit introduces the new c.enclosingOwner API that is going to serve
two purposes: 1) provide a better controlled alternative to c.enclosingTree,
2) enable low-level tinkering with owner chains without having to cast
to compiler internals.

This solution is not ideal, because: 1) symbols are much more than
I would like to expose about enclosing lexical contexts (after the
aforementioned discussion I’m no longer completely sure whether exposing
nothing is the right thing to do, but exposing symbol completers is definitely
something that should be avoided), 2) we shouldn’t have to do that
low-level stuff in the first place.

However, let’s face the facts. This change represents both an improvement
over the state of the art wrt #1 and a long-awaited capability wrt #2.
I think this pretty much warrants its place in trunk in the spirit of
gradual, evolutionary development of reflection API.

Subject: adds internal.changeOwner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per Jason’s and Mark’s request, this commit introduces `changeOwner`,
a facility to fixup symbol owner chains to prevent owner chain corruption
in macro expansions leading to crashes in LambdaLift and GenICode.

This is quite a low-level API that should only be used by expert users
to get their job done.

In the meanwhile we’ll be working on fixing the macro engine to
automatically prevent owner chain corruption in the first place:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Sometimes universe.internal just won’t cut it (for example, when internal
APIs need access to enclosingOwner or to the typechecker), and for that
we need c.internal.

It’s totally not a problem for us in Scala, because with first-class modules
we can just inherit c.internal from c.universe.internal and have it expose
all the basic APIs automatically. Yay for Scala!

Subject: adds internal.typingTransform
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per Jason’s request, this commit introduces a facility to perform
tree transformations that know how to track current lexical context
and how to typecheck trees in that lexical context.

Interestingly enough, we can’t get away with the traditional “subclass the
Transformer” approach, because the required base transformer class is
declared in scala-compiler.jar, and our API is defined in scala-reflect.jar.

This forced me to play with an idea that we’ve discussed with Denys today
(actually, it’s already yesterday) - lightweight transformers that take
contextful HOFs. This commit is a sketch in that direction. Turning
`transform` and `typingTransform` into macros would make the API more
elegant (see the comments), but I didn’t have time to experiment.

I’m running short on time, so I haven’t had a chance to actually test this API,
but I’m still submitting the pull request to ignite a discussion.

As per Denys’s request, this commit exposes the hack that we use to
obtain subpatterns of UnApply nodes. This is useful when writing
quasiquoting macros that do pattern matching.

Subject: some renamings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It’s almost 1am, so I’m only scratching the surface, mechanistically
applying the renames that I’ve written down in my notebook:
  * typeSignature => info
  * declarations => decls
  * nme/tpnme => termNames/typeNames
  * paramss => paramLists
  * allOverriddenSymbols => overrides

Some explanation is in order so that I don’t get crucified :)

1) No information loss happens when abbreviating `typeSignature` and `declarations`.
We already have contractions in a number of our public APIs (e.g. `typeParams`),
and I think it’s fine to shorten words as long as people can understand
the shortened versions without a background in scalac.

2) I agree with Simon that `nme` and `tpnme` are cryptic. I think it would
be thoughtful of us to provide newcomers with better names. To offset
the increase in mouthfulness, I’ve moved `MethodSymbol.isConstructor`
to `Symbol.isConstructor`, which covers the most popular use case for nme’s.

3) I also agree that putting `paramss` is a lot to ask of our users.
The double-“s” convention is very neat, but let’s admit that it’s just
weird for the newcomers. I think `paramLists` is a good compromise here.

4) `allOverriddenSymbols` is my personal complaint. I think it’s a mouthful
and a shorter name would be a much better fit for the public API.

Subject: SI-7044 deprecates Symbol.associatedFile

Before this commit, Symbol.associatedFile used to be broken in two ways.
Firstly, it was never autoloaded (just like we used to have flags,
privateWithin and annotations). Secondly, it was never filled in by runtime
reflection.

My first attempt at fixing those problems was, well, just fixing them.
However, its runtime implementation was based on a hacky function that
we were not very much excited about supported (see comments),
whereas its compile-time usefulness was somewhat questionable.

Therefore the second attempt at fixing this bug is deprecating the API
altogether, replacing it with `Symbol.pos.source`.

Since `Symbol.pos` isn't retained for runtime consumption,
`Symbol.pos.source` is still going to return `NoAbstractFile` as before
this commit, but that's left for future work, and suggested approach
is documented in SI-8259.

Subject: renames some methods in ReificationSupport

As per Denys's request, renames methods in ReificationSupport that are
eponymous to methods in Universe, so that we don't get nasty name
intersections.

This change is not source/binary-compatible, because we don't make any
promises about the contents of the build API. Feedback welcome.

I think that the "type" suffix here is redundant, so let's rename this API
to reduce the annoyance potential.

Subject: provides extension methods for internal

Based on my scala/async migration experiences, I can say that having
to write `setType(tree, tpe)` instead of `tree.setType(tpe)` is a major
pain. That's why I think it makes sense to expose some functions in internal
as extension methods.

Subject: makes internal.decorators signatures work

After fighting with path-dependent types to express wrappee.type,
I decided to take a different approach and replaced wrappee.type with
parametric polymorphism.

Subject: SI-6785 exposes Symbol.flags, setFlag and resetFlag

My first feeling was not to expose Symbol.flags, because that would
inevitably lead to exposing more methods on FlagSet. However we do need
flag manipulation in async, which is representative of advanced macros,
so I'm caving in.

Subject: fixes compat for tree and type extractors

When I removed XXXDef(...) and XXXType(...) methods from the public API,
I put compatibility stubs in compat via implicit classes enriching
XXXExtractor traits with apply methods.

Unfortunately, this doesn't work, because if XXXDef or XXXType have
any kind of an apply method left in the public API, then implicit classes
won't even be considered when resolving calls to XXXDef(...) or XXXType(...).

Therefore I had to put those removed methods back and adorn them with an
implicit parameter that can only be resolved when "import compat._"
is in place. Quite extravagant, yes, but goes along the lines with the
design goals of the refactoring, which are:

1) Break source compatibility for users who are using methods that are
now moved to internal in order to attract attention.
2) Provide an easy way to fix the breakage by importing compat._, which
will pimp back all the missing APIs with deprecation warnings that are
going to guide migration.

Subject: tests for SI-8300

Highlights the dilemma with rich type members in the cake that no longer
exists. One used to have to choose between overloading or patmat/extmeth
friendliness, but couldn't have both. Thanks to retronym we can have it all.

Subject: reverses SI-6484

Unfortunately I have to revert b017629 because of SI-8303. There are projects
(e.g. slick) that use typeOf in annotations, which effectively means bye-bye.

Subject: makes sure compat._ provides full compatibility with 2.10.x

This is extremely important to enable cross-versioning Scala 2.10 codebases
against Scala 2.11 using Jason's trick with:

  // TODO 2.11 Remove this after dropping 2.10.x support.
  private object HasCompat { val compat = ??? }; import HasCompat._

  def impl(c: Context)(...): ... = {
    import c.universe._
    import compat._
    ...
  }

Subject: improves situation with auto-init

Symbol.typeSignature and Symbol.typeSignatureIn no longer auto-init.
Neither does Symbol.toString (something that I introduced a few commits ago).
However Type.toString still does, and that should be enough to get
robust prettyprinting with minimal risk. Details are in comments.

Subject: undeprecates typeSignature and typeSignatureIn

As per Jason's feedback, these are now undeprecated, being aliases for
info and infoIn. I haven't touched the newly introduced setInfo family of
methods, because I think that on internal level we don't need setTypeSignature
anyway.
