Oh that's cool, it's a Python 3 thing though.

Thanks, I'll give that a try.

Yes you're right, I should have left that out, I noticed it after

There's another bug too, I think, if the length of the initial iterable
is exactly n. I better test that. So this was at best ok as a sketch
of the deque approach, not something to actually use ;)

Doesn't need all those separate tees, which per Srinivas Devaki would
use quadratic space.
