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.

* Improve readability and remove data dependencies by converting

pre-increment forms to post-increment forms. Post-incrementing
also eliminates the need for negative array indices for oparg fetches.

the older string based exceptions.

Since the fast_yield branch target was introduced, it appears that most
...
tests of "why" against WHY_YIELD became useless. This patch removes them,
but assert()s that why != WHY_YIELD everywhere such a test was removed.
The test suite ran fine under a debug build (i.e., the asserts never
triggered).
