Is that really such a common case? In Python 2.6 you can use next for the same
thing however without the check if there is just one item:
what_i_am_looking_for = next(filter(predicate, items))
What I would like to see is a batch function defined like that:
def batch(iterable, n):
return izip(*repeat(iter(iterable), n))
It's a common pattern I use it very often.

Armin
