Neither can I, and I've been mucking about with this idea for about
three years. (To be honest, I poke it with a stick about every six
months, so its not like I've spend a lot of time on it.)
I kinda-sorta got it to work with a class statement plus a decorator,
not too different from your metaclass example, but couldn't get
functions to work correctly.
But if I understand the original post here:

Batuhan Taskaya has got it to work using a dict. If that's the case,
that seems to be the hardest part done.
(On the other hand, if this is just a hypothetical "wouldn't it be cool
if this worked?" post, then we're actually no closer to a technical
solution.)
