>>> L = [1, 2, 3]
>>> len(L)
3
>>> I = iter(L)
>>> I
<listiterator object at 0x0091ABD0>
>>> len(I)
3
>>> I.next()
1
>>> len(I)
2
>>> I.next()
2
>>> len(I)
1
>>> I.next()
3
>>> len(I)
0
>>> I.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
StopIteration

(it's probably not a good idea to rely on this behaviour...)
