xrange returns an ITERABLE, not an ITERATOR.  Videat:

>>> a = xrange(23, 43)
>>> a.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'xrange' object has no attribute 'next'
>>> 

No next method -> not an iterator.  iter(xrange(...)) DOES return an
iterator, btw.
