It's good, but I think rebuilding the object through
new.instancemethod should be even better.
py> class A:
... def f(self):print "A"
...
py> class B(A):
... def f(self):print "B"
...
py> b=B()
py> b.f
<bound method B.f of <__main__.B instance at 0xa7d728cc>>
py> x = new.instancemethod(A.__dict__['f'], b, A)
py> x
<bound method A.f of <__main__.B instance at 0xa7d728cc>>
py> x()
A
py> b.f()
B
py> x.im_func.__name__,x.im_class,x.im_self
('f', <class __main__.A at 0xa7d7002c>, <__main__.B instance at 0xa7d728cc>)
On unpickling x, you'ld get x.(B.f), not x.(A.f) with your
approach.
Not sure it matters much.
