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.

* all usages of ClassManifest and Manifest are replaced with tags
* all manifest tests are replaced with tag tests

In the pursuit of simplicity and consistency.
- Method names like getType, getClass, and getValue are far too ambiguous,
both internally and especially with java reflection names. Methods which
accept or return scala symbols should not refer to them as "classes" in
the reflection library. (We can live with the FooClass convention for naming
the well-known symbols, it's names like "getClass" and "classToType" which
are needlessly conflationary.)
- Meaningless names like "subst" have to be expanded.
- We should hew closely to the terms which are used by scala programmers
wherever possible, thus using "thisType" to mean "C.this" can only beget confusion,
given that "thisType" doesn't mean "this.type" but what is normally called
the "self type."
- It's either "enclosing" or "encl", not both, and similar consistency issues.
- Eliminated getAnnotations.
- Removed what I could get away with from the API; would like to push
those which are presently justified as being "required for LiftCode" out of the core.
- Changed a number of AnyRefs to Any both on general principles and because
before long it may actually matter.
- There are !!!s scattered all over this commit, mostly where I think
the name could be better.
- I think we should standardize on method names like "vmSignature, vmClass" etc.
when we are talking about jvm (and ostensibly other vm) things.
There are a bunch more places to make this distinction clear (e.g.
Symbol's javaBinaryName, etc.)
- There is a lot more I want to do on this and I don't know where the
time will come from to do it.

The idea is that all operations that need to be synchronized are overriden in classes reflect.runtime.Synchronized*. Sometimes this applies to operations defined in SymbolTable, which can be directly overridden. Sometimes it is more convenient to generate SynchronizedClazz subclasses of SymbolTable classes Clazz. In the latter case, all instance creation must go over factory methods that can be overridden in the Synchronized traits.

Fix and re-enable test, that got broken by changes to reflection API in
rev 26014. Review by odersky.

Changed reflection to allow getting a Scala Symbol for the
implementation class of a trait.

Allow to load $class classes using Scala reflection.
Tweaked implementation of invalidClassName method
to exclude *$class clasess from the set of invalid
names. It's not exactly clear what was the intent
of this method in first place so I'm not sure if
it's the best way to fix SI-5176. Added test-case
that covers this issue.
Fixes SI-5176. Review by odersky.
