Builtn super() function. How to use it with multiple inheritance? And why should I use it at all?

EXCEPT for the last one, which must NOT call super!

The posted example happens to work because object has
a default __init__ method that does nothing. But this
is not generally true of other methods, which means you
need a "terminating" class at the end of the MRO whose
methods don't call super.
