Do you mean "the same thing" as in both return 'int', or "the same 
thing" is in __int__(3.4) == __index__(3.4) ?  Because that last one is 
False.

Hmmm -- so maybe you are saying that if the results of __str__ and 
__tostring__ are the same we're fine, just like if the results of 
__int__ and __index__ are the same we're fine?  Otherwise an error is 
raised.

Sounds reasonable.
