Well, I agree with you there.  The complexity introduced by super
typically outweighs the benefits it provides, IMO.  The only time when
it is really necessary is in non-trivial diamond inheritance
situations (to avoid calling the same method on some base class more
than once), and in those cases I think it is simply better to not use
multiple inheritance in the first place.

Cheers,
Ian
