What is range()?

help(range) shows me that range "Returns an iterator that generates
the numbers in the range on demand."

Ahá! So, as ints are unbound in Python, I could easily do:

>>> r = range(1,1000000000000000000000)

*If* range()  provides me the indexing facility (a nice feature to
have, but in any means core to this function), it should allow me to
index it completely, or at least, to Py_ssize_t. IOW, r[0] should
work, even if r[9999999999999999999) doesn't.

That is, to me, the range semantics that we should aim to.
