> The patch adds a new API function int PyObject_AsIndex(obj)
How did you decide between int and long?
Why not ssize_t?
Also, if index is being added as a builtin, should the failure
result be changed? I'm thinking that this may become a
replacement for isinstance(val, (int, long)). If so, it might
be nice not to raise errors, or at least to raise a more
specific subclass. (Catching a TypeError and then
checking the message string ... does not seem clean.)
