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

My contention is that nobody has any chance of guessing what
it does based on the name "super". Superness doesn't come into
it at all, except in the trivial sense that whatever class it
picks will be in the mro of the second argument, which doesn't
narrow it down much.

So the word "super" here is little better than meaningless noise.

If it were something like next_method(C, self) then one could
claim with some justification that it stands for "call the next
method found after C in the mro of self".
