Looks good to me. Only change I might make is mention why int doesn't work sooner (such as in the rationale). Otherwise +1 from me.

I have a slight reservation about the name. On the one hand it's clear the canonical use will be for indexing sequences, and index doesn't look enough like int to get people confused on the difference. On the other hand, there are other places (in C) that want an actual int, and they could use index too. Even more so if a PyArg_Parse* grew a format for 'the index-value for this object' ;)

On the other one hand, I can't think of a good name... but on the other other hand, it would be awkward to have to support an old name just because the real use wasn't envisioned yet.
