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-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.

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]
- *    ...
- *  }
- *  }}}

+   *
+   *  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

+  /** 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.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]
+   *    ...

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: 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._
    ...
  }
