Yes! With the calling syntax extension that I
have proposed before, that would be written

   Base.__init__(self, x, y, **kw)

Still requires the self argument, but I think
you'll agree it's a lot better than having to
use apply!

I'd also like a way of getting rid of the self
argument in that situation as well, but this seems
to be quite a difficult problem to solve within
Python's existing execution model. I haven't
thought of a good solution yet.
