Really?  Unless I misunderstood the docs, __index__ is used when the
object is used as an index (or with bin or oct, but I didn’t want to
complicate the docstring, just fix it).

On IRC, R. David Murray said that I could just have deleted the
docstring.  I agree with that: I think magic methods never need a
docstring, since they’re documented once and for all in the language
reference.  (__init__ is not an exception: its parameters can be
documented in the class docstring.)

The fact that __index__ is implemented thanks to int/__int__ here is a
detail IMO.
