In Python 3.3:

... super().__init__(*args) # does nothing, call it anyway

Traceback (most recent call last):

File "<stdin>", line 3, in __init__
TypeError: object.__init__() takes no parameters
It is apparently an oversight, or a bug, that it ever worked in older
versions.
I'm not really convinced that the overall behaviour is sound:
py> x = 42
py> x.__init__()
py> x.__init__(1)
py> x.__init__(1,2)
py> x.__init__(1,2,3)
py> x.__init__(1,2,3,4)
Neither of these seem to care about the number and type of parameters.
On the other hand:
py> y = object()
py> y.__init__()
py> y.__init__(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: object.__init__() takes no parameters
So, for some reason that I don't understand yet, my call to the
superclass' init function skips a class, but only when called with super().
Confused greetings!
