[Python-ideas] Object adaptation and interfaces and so forth

(Not exactly an idea post, but I don't want to bother python-dev or python-3000 with this.) PEP 246 was rejected a year or so ago, and Guido's rejection note stated "Something much better is about to happen; it's too early to say exactly what, but it's not going to resemble the proposal in this PEP." Does anyone know if anything has gone on with this concept since then? It seems like it has a lot of really interesting potential, although I do see why PEP 246's specific proposal was rejected. It's just the "Something much better is about to happen" that got me curious -- is it happening yet? :)
