generator object, next method

[simonwittber at gmail.com]

>>> gen = iterator()
>>> gen.next
<method-wrapper object at 0x009D1B70>
>>> gen.next
<method-wrapper object at 0x009D1BB0>
>>> gen.next
<method-wrapper object at 0x009D1B70>
>>> gen.next
<method-wrapper object at 0x009D1BB0>
>>> gen.next is gen.next
False


What is behind this apparently strange behaviour? (The .next method
seems to alternately bind to two different objects)
