Neal Norwitz 37c0844b35 Fix SF bug #1167751, Argument genexp corner case 
Incorrect code was generated for:

  foo(a = i for i in range(10))

This should have generated a SyntaxError.  Fix the Grammar so
it raises a SyntaxError and test it.

I'm uncertain whether this should be backported.  It makes
something that was Syntactically valid invalid.  However,
the code would either be completely broken or do the wrong thing.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head 
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Phillip J. Eby 0d6615fd29 PEP 342 implementation. Per Guido's comments, the generator throw() 
method still needs to support string exceptions, and allow None for the
third argument.  Documentation updates are needed, too.

Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation 
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.
