You must spell out the parent explicitly, otherwise subclasses call
super() with themselves rather than the correct parent class.
self.__class__ is too dynamic here. Have a look at this example:

class A(object):
    def method(self):
        pass

class B(A):
    def method(self):
        super(self.__class__, self).method()

class C(B):
    pass

In this example, C().method() results in "super(C, self).method()"
because self.__class__ is C. However that is wrong because you have to
call super() with the direct parent.
