Well, during the execution of the class statement the function is not
yet a method:

>>> class C:
...     def f(self):
...             print self
...     print type(f)
... 
<type 'function'>

and you can get rid of f with del afterwards:

>>> class C:
...     def f(self):
...             print self
...     f(1)
...     del f
... 
1
>>>
