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.
