Hi group,
I am trying to use a weak reference to a bound method:
class MyClass(object):
def myfunc(self):
pass
o = MyClass()
print o.myfunc
>>>> <bound method MyClass.myfunc of <__main__.MyClass object at 0xc675d0>>
import weakref
r = weakref.ref(o.myfunc)
print r()
>>>> None
This is what I do not understand. The object "o" is still alive, and
therefore the bound method "o.myfunc" shall exists.
Why does the weak reference claim that it is removed? And how can I hold
the reference to the method until the object is removed?
Is this a bug or a feature? (Python 2.6)
Best regards
Ole
