That's actually not quite right. The first argument to super() has
to be the class whose implementation of the method is currently being
run (i.e., the class whose implementation is calling super). This is
not always the same as the class of the instance. If A uses super to
call B's implementation of a method, and B tries to use
super(self.__class__, self), then self.__class__ will still be A, and
infinite recursion will result. See
http://stackoverflow.com/questions/4235078/how-to-avoid-infinite-
recursion-with-super .
