The new magic super() uses a similar, hidden, compiler-activated hack
to work properly:

>>> class C:
...     def f(): super
... 
>>> C.f.__closure__
(<cell at 0x7fe2bb402e98: type object at 0x14ec5e0>,)
>>> C.f.__closure__[0].cell_contents
<class '__main__.C'>


>>> sup = super
>>> class D:
...     def f(): sup
... 
>>> D.f.__closure__
>>>
