>>> class A(object):
... def a(self):
... print 'a'
...
>>> ins = A()
>>> ins
<__main__.A object at 0x7f539e012250>
>>> ins.a
<bound method A.a of <__main__.A object at 0x7f539e012250>>
>>> l = []
>>> l.append(ins.a)
>>> l
[<bound method A.a of <__main__.A object at 0x7f539e012250>>]
>>> del ins
>>> l

>>> m = l[0]
>>> m
