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.

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.

The original commit message (from 54a84a36d5):
SI-6548 reflection correctly enters jinners
When completing Java classes, runtime reflection enumerates their
fields, methods, constructors and inner classes, loads them and
enters them into either the instance part (ClassSymbol) or the
static part (ModuleSymbol).
However unlike fields, methods and constructors, inner classes don't
need to be entered explicitly - they are entered implicitly when
being loaded.
This patch fixes the double-enter problem, make sure that enter-on-load
uses the correct owner, and also hardens jclassAsScala against double
enters that can occur in a different scenario.

Originally composed to accommodate pull request feedback, this test has
uncovered a handful of bugs in FromJavaClassCompleter, namely:
* SI-7071 non-public ctors get lost
* SI-7072 inner classes are read incorrectly
I'm leaving the incorrect results of FromJavaClassCompleters in the check
file, so that we get notified when something changes there.

Runtime reflection in JavaMirrors previously forgot to fill in
privateWithin when importing Java reflection artifacts. Now this is fixed.
