[Python-ideas] simpler super() syntax

[Guido van Rossum]

(a) In Py3k, you will be able to use super() itself without args, e.g.
super().__init__(*args)

(b) There are lots of reasons why you would not want to pass the args
to your super method *unchanged*. Also, super methods may have
defaults for all args. So super.__init__() would be ambiguous -- does
he want to pass all args or none?

Because of this I am strongly against this.
