Ahh, so you expected that ``Wrapper(self._foo)`` would not immediately
lose the reference? It will, because every time you write
``self._foo``, a new bound method is created::
>>> class C(object):
... def foo(self):
... pass
...
>>> f = C.foo
>>> g = C.foo
>>> id(f), id(g)
(14931448, 14891008)
Thus, there is only the one reference to the bound method, and by
wrapping it in a weakref, you are allowing it to disappear immediately::
>>> x = weakref.ref(C.foo)
>>> print x()
None
What behavior do you want here? That is, when were you hoping that the
bound method would disappear?
