Add a more informative message for the common user mistake of subclassing
from a module name rather than another class (i.e. random instead of
random.random).
(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.
pre-increment forms to post-increment forms. Post-incrementing
also eliminates the need for negative array indices for oparg fetches.
* In exception handling code, check for class based exceptions before
the older string based exceptions.
BINARY_SUBSCR:
* invert test for normal case fall through
* eliminate err handling code by jumping to slow_case
LOAD_LOCALS:
* invert test for normal case fall through
* continue instead of break for the non-error case
STORE_NAME and DELETE_NAME:
* invert test for normal case fall through
LOAD_NAME:
* continue instead of break for the non-error case
DELETE_FAST:
* invert test for normal case fall through
LOAD_DEREF:
* invert test for normal case fall through
* continue instead of break for the non-error case
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).
* Defer error handling for wrong number of arguments to the
unpack_iterable() function. Cuts the code size almost in half.
* Replace function calls to PyList_Size() and PyTuple_Size() with
their smaller and faster macro counterparts.
* Move the constant structure references outside of the inner loops.

disables opcode prediction when dynamic execution
profiling is in effect, so the profiling counters at
the top of the main interpreter loop in eval_frame()
are updated for each opcode.
Simplified version of Neal Norwitz's patch which adds gotos for
opcodes that set "why". This skips a number of tests where the
outcome of the tests are known in advance.
