impressively tedious it is to work directly with the AST, so I picked up
TreeDSL again and fleshed it out some more. And then I did a once over
on SyntheticMethods beating out bits of duplication. No review.

Fixed long standing annoyance which prevents the same source file from
being used as both a script and a program. If a script has only a single
top level object with a main method, then that is the object to which
arguments will be passed. (Contrast with the current situation, where
a wrapper object is wrapped around it and the script will never do
anything since there is nothing which can reference the object.)
So now you can do this:
% cat script.scala
object FiddleDeeMain {
def main(args: Array[String]): Unit = {
println(args mkString " ")
}
}
% scala -nocompdaemon script.scala a b c
a b c
% scala script.scala a b c
a b c
% scalac script.scala
% scala FiddleDeeMain a b c
a b c

Restoring negative literal parsing behavior to what should be the least
surprising option. Thanks much to Johannes Rudolph for identifying the
bug in the bytecode generator which needed addressing for us to arrive
at proper -0.0 behavior, and for writing the majority of this patch.
A '-' followed immediately by either a number or a period should now
always be treated as a single numeric literal, which means the minus
binds more tightly than anything else. A specific example of how this
differs from 2.8 final is:
-5.+(10) == 5.0 // and not -15.0
The full range of potentially ambiguous parses involving prefix
operators, numbers, and dots is quite large and still needs to be
completely and clearly specified.

Some tweaks to ListSet to make it less pathological in its outlook. We
can see some modest improvements in run time and answer quality via the
enclosed test case:
// with this patch: 2.250s elapsed, assertions pass.
// without this patch: 51.441s elapsed, and it's
a mercy killing: java.lang.StackOverflowError at
scala.collection.immutable.ListSet$Node.contains(ListSet.scala:117) at
scala.collection.immutable.ListSet$Node.contains(ListSet.scala:117)

part 2 of the dependent method refactoring: improved interaction with
implicit search (needed for oopsla paper)
more to come in this area, see e.g. #3346 (stanford edsl stuff)
reopens #13, which wasn't fixed properly before imo, anyway (have a look at -Xprint:typer output before this commit: a type that's not expressible in surface syntax is inferred -- also removed duplicate test file)
closes #3731: co-evolve type alias type symbols when their rhs is
updated and they are referenced by type selections (see typemap)

closes #1569, #3731: refactored dependent method types to get rid of
debruijn indices and use singleton types instead.
this is the core of the dependent types refactoring, no implicit or
inference changes
(one baffling discovery: resultType should drop annotations that don't subclass TypeConstraint, even in the trivial case... wow -- thanks to Tiark for helping me figure it out on a terrace in Barcelona
TODO: probably need a more principled approach to the propagation of plugin type-annotations)

the Transform-derived traits within view resisted evaluating the entire
sequence on a toString call, but the original view returned from a call
to .view did not. This has a particularly bad result in the case of
Stream, as for instance:
Stream from 1 view
would enter infiniteloopiland in the repl despite the fact that it
should be doubly resistant to eager evaluation.

positioning fix for infix expressions: report error at the operator
instead of at the receiver of a binop
In general use the operator position as the Select position's point
instead of the left or right expression. Position.union always uses the
receiver's point as point of the result, so swapping fixes that.
See http://www.scala-lang.org/node/6912 for the report.

Couldn't bear to see sbt seemingly so close but still unable to run
tests. Made some progress but bogged down in scalacheck when I realized
things were farther from working than I'd thought. Please forgive this
brief expression of frustration, because the despair is palpable:
the weeks of work I did on partest was apparently of no interest,
and now I'm in here having to fix the same partest bugs again, in a
more virulent form. They've evolved into some kind of ant-partest-sbt
artificial creature, more fearsome than any one of them could be under
its own power.
Did we not know we have a whole directory full of pretty code like this?
List(
"Scala compiler classes in: " + testBuildDir,
"Scala version is: " + nsc.Properties.versionMsg,
"Scalac options are: " + universe.scalacOpts,
"Java binaries in: " + javaBin,
"Java runtime is: " + javaInfoString,
"Java runtime options: " + (Process.javaVmArguments mkString " "),
"Javac options are: " + universe.javacOpts,
"Java options are: " + universe.javaOpts,
"Source directory is: " + src,
"Selected categories: " + (selectedCategories mkString " "),
""
) mkString "\n"
It's src/partest-alternative in case anyone wants to consider any of it.
At the very least there are individual files or functions which could be
cherry picked.
-- This patch contains: --
Readability efforts. Twelve parameter functions whose last six
parameters are "true,true,failedOnly,true,false,log" are pretty
challenging to work with.
Changes to the environment variables sbt was setting to look a bit more
like what partest expects and will crash without.
Sets partest.debug=true if the sbt logger level is at Debug.
On my machine all test groups except scalacheck appear to run to
completion.
Review by moix. (Hello, moix! I am available for assistance if you are
in the market for it. You have brought us long suffering ant-ers to the
brink of sbt goodness: and now, we enter the fray!)

Interpreted absence of any objections in mailing list thread
http://www.scala-lang.org/node/7398 as implicit encouragement to
proceed. Adds complementary implicits to Predef such that the eight
primitive types are both boxed and unboxed as the occasion demands.
