Me too. :-)
But... What does it do? PEP says:
In the new model, the syntax for specifying a metaclass is via a keyword argument in the list of base classes:
class Foo(base1, base2, metaclass=mymeta):
...Additional keywords will also be allowed here, and will be passed to the metaclass, as in the following example:
class Foo(base1, base2, metaclass=mymeta, private=True):
...Who is the receiver of the implements keyword argument in your example? Should it not be class class C(metaclass = SomethingHere, implements = (I1, I2))?
