Thanks, Alex! Now let's pass this on to Michel, then...
I've been reading your PEP 245 now and this fits very
much what I'd expect Python interfaces to look like.
What is the state of the art with it?
The Wiki supposed to discuss this is pretty inactive
isn't it? And what is the relationship to PEP 246 for
which I have not seen any place to discuss it?

and the project goes down the drain."
