Removing metaclass in Python 3000 -------------------------------------

As a side-effect of its generality, the make-statement mostly eliminates the need for the _metaclass_ attribute in class objects. Thus in Python 3000, instead of:: (...)

One of the reasons that this PEP was born is because metaclasses are being used in ways that don't look natural to some, like generating interface instances out of a class statement, so this would add an interesting way to support these constructs.

That doesn't look like a good reason, though, to kill the metaclass support that Python took so long to maturate. Otherwise, a new optional extension could be included as well: "Removing the 'class' statement".
