 This behavior is self-evidently wrong, and seems to
be due to an
implementation detail of Python. There is a workaround
available here:

(I haven't
examined it closely, but it looks like it should work)
 Nevertheless, this
should be fixed eventually IMO.

I fail to see a bug here. x.bar creates a new object (a
bound method),
for which then a weak reference is created. Since there is
no strong
reference to the same bound method, the bound method is
deleted, and
the weak reference dies.
