But my original point still stands. dictiter_getiter, enum_getiter,
iter_getiter are all fairly clear: they get the iter for an (existing)
dictiter/enum/iter object. PyObject_GenericGetIter does not return an
iterator for a generic object, it's a generic way to return an iterator
*for an iterator*. PyIter_GenericGetIter, PyObject_IterGetIter, etc are
all more descriptive.

I also agree with Guido on that this should not be a public API function
(and if it is, it should be documented <wink>.) Functions that aren't
part of the public API but can't be static should be prefixed with _Py.
