the code here becomes much simpler.  In particular: abs(), divmod(),
pow(), int(), long(), float(), len(), tuple(), list().

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.

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.

(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.

Following is a context diff for imaplib.py in the Python1.5.1 distribution.
It fixes 2 bugs. One to do with argument quoting, and the other to do with
caching of un-tagged responses. Apologies for its size.
