>>> from copy import deepcopy
>>> from itertools import count
>>> c = count()
>>> c.next()
0
>>> deepcopy(c)
count(0)
>>> c.next()
1
>>> deepcopy(c)
count(0)
>>> c
count(2)
>>> deepcopy(c).next()
0


I don't see any reason why these shouldn't be deepcopyable (or picklable
for that reason - and that fails too)
