I guess, I'm just asking for enumerate to go through the same change that range went through.  Why wasn't it a problem for range?

Ah good point.  Well, in the case of a sequence argument, an enumerate object could be both a sequence and an iterator.

>>> issubclass(collections.Sequence, collections.Iterator)

>>> issubclass(collections.Sequence, collections.Iterable)
