New submission from Claudiu Saftoiu:
Right now, itertools.permutations and itertools.combinations and
itertools.product objects don't have a `len`.
>>> len(itertools.combinations(range(10), 5))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: object of type 'itertools.combinations' has no len()
I propose that a `len` be added to them, which computes (& caches) & returns
the length. If the underlying iterator doesn't have a length, then they can
raise a TypeError as they do now.
