It *isn't* a big deal; but it'd still be nice, and I'd happily volunteer to
do the actual implementation of the 'close()' method myself, because it's
about the same amount of work as updating PEP 333 and sorting out any

But it does exist, alas; see the 'itergroup()' and 'xmap()' functions of

http://www.python.org/doc/lib/deque-recipes.html
And there are other examples as well:
