This is very close to acceptance. I think I'd like to see the patch developed and submitted to SF (and assigned to me) prior to acceptance.

Copyright This document is placed in the public domain If you agree with the above comments, please send me an updated version of the PEP and I'll check it in over the old one, and approve it. Then just use SF to submit the patch etc.

I uploaded a patch to SF against current SVN. The altered code compiles and the functionality works with classes defined in Python. I have yet to test against a C-type that defines the method.

The patch adds a new API function int PyObject_AsIndex(obj).

This was not specifically in the PEP but probably should be. The name could also be PyNumber_AsIndex(obj) but I was following the nb_nonzero slot example to help write the code.
