Some refinement of the error messages when the found and required types
have the same simple names. No longer must we watch people scratch their
heads at such messages as:
found : scala.collection.Set[String]
required: Set[String]
Now so clear you could enjoy a movie through it:
found : scala.collection.Set[String]
required: scala.collection.immutable.Set[String]
No review.

closes #1693: improve implicit conversion disambiguation by
incorporating the expected type of the member that triggered the
conversion
back-ported fix by Martin in embeddings branch.

Finally completed the incredibly tedious task of removing the lower case
primitive aliases from Predef. Had to rebuild msil.jar along the way.

- MethodTypes now have (params: List[Symbol])
- "copy"-methods for case classes
- the "copy" object in the compiler is now called "treeCopy"

changed overloaing resolution to make Builders work. generalized
companion object generation in Namers. Fixed a problem in Types that
made the collection build crash.

suppress "scala." prefix in string representation of types (in error
messages,..)

- prefixString in SingleType suppresses scala.Predef prefixes
- (sym.isPredefModule) better handling of double defs of `_' in type
- params (now in enterInScope in Namers) introduced HKmode to indicate
- we're typing a higher-kinded type, instead of reusing POLYmode |
- TAPPmode
- Typers.typedTypeConstructor does not normalize the result anymore -- now in GenICode
generatedType = toTypeKind(tpt.tpe.normalize)

2. More detailed error messages for ambiguous implicits. 3. Relaxed
rules for necessary overlap in pattern matching

Removed a DOS-style new line character from test/neg/implicits.check
|
|
|
added "Function" module to library/scala
