As long as they wanted to use longs, that's fair.  E.g. now that we're
trying to get rid of the difference between ints and longs, something
like range(0, 2**100, 2**99) should really just work (and it better
give us [0, 2**99] :-).

Thanks.  I had hoped to release beta1 before PyCon, but that's not
realistic.  But I'll work on it soon after.

That's something for Raymond H.
