There's been a few times I've wanted a function like
this. I keep expecting that len(iterable) will work,
but of course it doesn't.
Would itertools.len(iterable) be useful? More likely
the name collision with len itself would be a problem,
so perhaps itertools.length(iterable).
BTW, I saw itertools.count and figured that might be
it. Nope. And don't try the following
>>> import itertools
>>> print list(_)
