The iterator was then the integer you passed to __getitem__()?
Many people would consider that a *very* limited form of
iterator.

The ability to have several independent and concurrent iterators
for a single sequence object was not there.  At least not if you
wanted it to be efficient.  And several other things you can do
with proper iterators were more than "a bit" more difficult to
implement.

Sure, you could *implement* iterators in Python, but that's
not the same as there *being* iterators.  By that reasoning,
you could say that C and Pascal has iterators, or that MS-DOS
has multitasking (you could always load a multitasker, like
MS Windows, on top of MS-DOS).
