I checked in two itertool representations that were clear-cut:
;-)
>>> from itertools import count, repeat >>> count(20) count(20)
Is the representation (of the dynamic object) static? Does
it=count(20); it.next(), it.next(); it
still print 'count(20)' as it one was but no longer is?
This seems much like lt=iter([1,2,3]); lt.next(); lt.next(); lt printing iter([1,2,3]) instead of iter([3]), or worse, lt=[1,2,3]; lt.pop(); lt.pop(); lt printing [1,2,3] instead of [1].
