been ignoring their painstakingly set classpaths and using whatever they
can find in the vicinity of the scala script, which works OK for pack
but not so well for quick.
I also added a build.xml feature so you can drop jars into a dir
and have them automatically used everywhere. The directory is
lib/extra. Pro tip: add lib/extra to .gitignore and put jars like
yjp-controller-api-redist.jar in there.

Another exciting development in the world of -Y options which I and
three other people will use. Today's is -Yrich-exceptions. Use it like
so:
SOURCEPATH=/path/to/src scalac -Yrich-exceptions a.scala
In the repl, -Yrich-exceptions will cause lastException to be bound to
an Exceptional instead of old rusty Throwable. That spins up new powers:
scala> Nil.head
[Nil.head] (List.scala:389)
(access lastException for the full trace)
scala> lastException.show
/* The repl internal portion of the stack trace is elided. */
[Nil.head]
386: override def isEmpty = true
387: override def head: Nothing =
388: throw new NoSuchElementException("head of empty list")
*389: override def tail: List[Nothing] =
390: throw new UnsupportedOperationException("tail of empty list")
391: // Removal of equals method here might lead to an infinite recursion similar to IntMap.equals.
392: override def equals(that: Any) = that match {
[line0.<init>] (<console>:6)
[line0.<clinit>] (<console>:-1)
Also try "lastException.showTable" but this is getting a little long for
more excerpt. No review.

This should fix java signatures when they refer to

Half of an implementation of sealedness for java enums. Since it's only
half it's behind -Xexperimental, but it works like a charm for the half
where it works (that being compiling against bytecode.) Need input on
how to approach the source half. References ticket #2442. Review by
moors.

Some more work on options related to showing compiler structures during
compilation. The pickler knew more than was healthy about things like
compiler settings, so I let the pickler worry about pickling and moved
that logic somewhere closer to the surface. Some convenience oriented
tweaks to command line phase parsing. The end result is as follows (some
output trimmed for brevity.)
// dippy.scala
class Dippy {
def f[T <: Dippy](x: T) = (x, x)
object DingusDippy extends util.Random { }
}
// className@phaseString should be reliably unambiguous
% scalac -Xshow-class Dippy@typer,erasure,jvm dippy.scala
<<-- class Dippy after phase 'typer' -->>
Members (excluding Any/AnyRef unless overridden):
final object DingusDippy extends object Dippy.this.DingusDippy
def f[T <: Dippy](x: T): (T, T)
<<-- class Dippy after phase 'erasure' -->>
Members (excluding Any/AnyRef unless overridden):
private lazy var DingusDippy$module: object Dippy#DingusDippy
lazy val DingusDippy(): object Dippy#DingusDippy

Introduces "Origins" for all your superhero backstory needs. It logs

While investigating the cause of #3984, discovered that set hashcodes
were being calculated like:
elems map (_.hashCode) sum
This looks totally correct, except that because of set+map semantics it
drops all the duplicate hashcodes and therefore calculates the wrong
sum anytime there are unequal elements with equal hashcodes. If we're
married to the set+map semantics (and I don't know what could be done
about it) I had better get a proper -Xlint going because this is one of
those traps which shoots bees out of its mouth. No review.

the same issues as JavaConversions with respect to overloading implicit

unwittingly suffering degraded functionality. No review.

distribution can now be built with that option, with or without
optimization, and almost all tests cases can. (Those which can't are due
to different -Ycheck: issues.)
Major changes of interest are as follows:
* LOAD_EXCEPTION and THROW are parameterized on the throwable symbol.
* Does not squash all traits down to AnyRef, but instead deals with
issues as they arise. By observation the cases where one needs a "Foo
with Product" to manifest as both a "Foo" and a "Product" at different
places are quite rare, so we need not throw out the whole baby. *
Exception handlers now have positions. * The remaining checker failures
removed, such as CALL_METHOD wanting to pop a value off the stack
after calling a constructor. * Many multiply defined values such as
REFERENCE(ObjectClass) put in one place (ICodes.scala) and reused. *
-Ycheck:icode output (if also given -Ydebug) worthy of Michelangelo.
Here is a class and the -Ycheck:icode -Ydebug output for f's block.
class A {
def f(x: Int, y: String) =
try println(x + y.length)
catch { case x: NullPointerException => () }

Modified the lub calculation in TypeKinds to avoid the icode checker
failures described in ticket #3872. This does not alter the compiler's
lub calculation as I'd hoped because I could not figure out how to
accomplish this without having unintended consequences. I think that
either Symbol.isLess could be adjusted, or perhaps the implementation of
spanningTypes, or other places... but it eluded me and I defer to the
type wizards. No review.

A bit of -Xshow-class / -Xshow-object which didn't quite make the Global
patch. Now type selections should do the right thing, e.g.
scalac -Xshow-class Global#Run

even more thrills. No review.

consistently, and remove things which are not being used anywhere
in the visible universe. Beyond general polish here are some of the
feature-like additions I can remember:
* -Xshow-phases now includes descriptions of the phases.
* -Xshow-class and -Xshow-object did not work as far as I could tell:
if they didn't, now they do. If they did, now they work better.
And you don't have to give it a fully qualified name anymore.
* -Xprint-icode will generate *.icode files (don't also have to say -Xprint:icode)
* counts of deprecation and unchcked warnings are given
* More documentation of what global is doing.
I tried not to break anything which might be using Global, but let me
know if I overshot somewhere. No review.

Determined that half a dozen ways of checking for varargs and
by-name-ness in param lists exceeded the legal limit. Also assessed that
names which are only used as type names would be a lot easier to deal
with if we created them as type names up front. Performed the changes
implied by the preceding along with a partial cleanup on TreeInfo which
one can see hasn't had a good look in a long time. (And still hasn't.)
