[New-bugs-announce] [issue7410] deepcopy of itertools.count resets the count

[Robert Collins]

New submission from Robert Collins <robertc at robertcollins.net>:

>>> 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)
