Tim Peters 88459359b1 Fix one of the tests that fails on the "x86 OpenBSD trunk" buildbot, due
to that id() may return a long on a 32-bit box now.  On a box that assigns
addresses "with the sign bit set", id() always returns a long now.

Jeremy Hylton c960f26044 Improved handling of syntax errors.
Expand set of errors caught in set_context().  Some new errors, some
old error messages changed for consistency.

Fixed error checking in generator expression code.  The first set of
tests were impossible condition given the grammar.  In general, the
ast code uses REQ() for those sanity checks.

Fix some error handling for augmented assignments.  As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it.  Should come back to this.

Add note to Grammar that yield expression is a special case.

Add doctest cases for SyntaxErrors raised by ast.c.

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.
