Make sure that no tp_as_numbers->nb_<whatever> function is called
without checking for a NULL pointer. Marc-Andre Lemburg will love it!
(Except that he's just rewritten all this code for a different
approach to coercions ;-( )
swapped arguments].
Also make sure that no use of a function pointer gotten from a
tp_as_sequence or tp_as_mapping structure is made without checking it
for NULL first.
the code here becomes much simpler. In particular: abs(), divmod(),
pow(), int(), long(), float(), len(), tuple(), list().

A few other cosmetic things, such as properly reindenting slice().
programming style.
Recoded many routines to incorporate better error checking, and/or
better versions of the same function found elsewhere
(e.g. bltinmodule.c or ceval.c). In particular,
Py_Number_{Int,Long,Float}() now convert from strings, just like the
built-in functions int(), long() and float().
Sequences and mappings are now safe to have NULL function pointers
anywhere in their tp_as_sequence or tp_as_mapping fields. (A few
places in other files need to be checked in too.)
Renamed PySequence_In() to PySequence_Contains().
old value in a temporary and XDECREF it only after then new value has
been set. This prevents the (unlikely) case where the destructor of
the member uses the containing object -- it would find it in an
undefined state.
targets. On some platforms this would cause an infinite Make
recursion. Also remove "Doc" from the SUBDIRSTOO variable, since it
no longer exists in the standard distribution.
(py-execute-import-or-reload): Cool new command that imports or
reloads the current file as a module, so as not to clutter the global
namespace. Bound to C-c C-m.
(py-execute-def-or-class): New command that sends the current def or
class to the interpreter. Bound to C-M-x.
(py-execute-string): New command that sends arbitrary string to the
interpreter. Not bound by default.
(py-describe-mode): Doco updates.
py-beginning-of-def-or-class, and defaliased for backwards
compatibility. ME patch to add optional second argument, count.
(end-of-python-def-or-class): Renamed to py-end-of-def-or-class, and
defaliased for backwards compatibility. ME patch to add optional
second argument, count.
because the path through the code would notice that sys.__path__ did
not exist and it would fall back to the default path (builtins +
sys.path) instead of failing). No longer.
(py-shell): Recognize the Python debugger prompt
(py-jump-to-exception): Force into python-mode any buffer that gets
jumped to on exception. Cope with py-exception-buffer possibly a
cons.
