Hey Martijn, this is the idea I was talking to you about on gtalk.

+1 from me as well.

Would it make any difference one way or the other if we used
"classProvides()" instead of "implements()" for this? Conceptually, I
think it makes more sense to declare that a class provides a certain
interface if we want to grok it. "implements()" declares things about
what the future instance provides instead of declaring things about
the class.

In this case we could even use the the component architecture itself
to look up the grokkers for a class (would that even make sense?).

Cheers, Leo
