How to make super() work by manually filling the __class__ cell?

Question

In Python 3 one can use super() instead of super(MyClass, self), but this only works in methods that were defined inside the class. As described in

Answer 1

You can use the function's dictionary.

def f(self):
    super(f.owner_cls, self).f()
    print("B")

def add_to_class(cls, member, name=None):
    if hasattr(member, 'owner_cls'):
        raise ValueError("%r already added to class %r" % (member, member.owner_cls))
    member.owner_cls = cls
    if name is None:
        name = member.__name__
    setattr(cls, name, member)

class A:
     def f(self):
         print("A")

class B(A):
     pass

add_to_class(B, f)

B().f()

You can even add another attribute member_name if you don't want to hardcode the name of the name of the member inside the function.
