[Python-3000] PEP for Metaclasses in Python 3000

[Greg Ewing]

Some more metaclass syntax ideas:

   class Foo[Meta](bases):
     ...

   Meta class Foo(bases):
     ...

although I don't like the way the latter moves the
'class' keyword away from the beginning.

Another thought: It's not strictly necessary to
allow for arguments to the metaclass, since the same
effect can be achieved with a factory function, like
we do for decorators.
