When you say "problems" with xrange or itertools.count hitting maxint,
the correct word is "bugs". The right thing to do with library bugs
is fix them, not clutter up your application code to circumvent them.
xrange, at least, raises an error if you give it too large an
argument, but what itertools.count does is just plain dangerous.
I just opened SF bug 1326277 about itertools.count.
