The examples use lists because I was using doctest and needed
checkable output. But I think it should work fine with any (finite)
iterator. I don't see a problem with the algorithm if I use infinite
iterators (the algorithm is one-pass and generates results on demand)
but I haven't tested it explicitly.
Yep, looks OK:
>>> import itertools
>>> c1 = itertools.count()
>>> c2 = itertools.count(3)
>>> output = comm(c1, c2)
