[Python-Dev] [Python-3000] Stabilizing the C API of 2.6 and 3.0

[Lisandro Dalcin]

Chistian, I've posted some weeks ago some observation about the status
of PyNumberMethods API. The thread link is below, I t did not received
much atention.

http://mail.python.org/pipermail/python-3000/2008-May/013594.html

Now I sumarize that post

* 'nb_nonzero' was renamed to 'nb_bool'
* 'nb_inplace_divide' was removed
* 'nb_hex', 'nb_oct', and 'nb_coerce' are there, but they are unused

IMHO, the PyNumbersMethods struct should be left as in Py2, or it
should be cleaned up, that is, all unused slots should be removed.
