Let me add the following example on my post:

>>> class Bogus:
... 	def __init__(self, n):
... 		self.n = n
... 	def __iter__(self):
... 		return range(n)
... 	
>>> a = Bogus(10)
>>> a.next()
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
AttributeError: Bogus instance has no attribute 'next'
