New submission from Roman Rader:
Some strange behavior is observed while method in object substitutes with
callable object.
For example:
-------------------------------------
class Meth(object):
def __call__(*args, **kwargs):
print (args, kwargs)
class X(object):
def some_method(*args, **kwargs):
print (args, kwargs)
x = X()
x.some_method(1)
X.some_method = Meth()
x.some_method(1)
-------------------------------------
Output
(<__main__.X object at 0xb72d408c>, 1) {}
(<__main__.Meth object at 0xb72d40cc>, 1) {}
-------------------------------------
So, second call lost caller object ("self").
I suppose second output should be
(<__main__.Meth object ...>, <__main__.X object ...>, 1) {}
Tested in Python 2.7 and Python 3.3.
