Jack, it seems I misunderstood you (slightly?).
I was talking about the other direction (constructing Python objects
from C pointers or handles).
I had to invent a special convention: I use O& with a function which
calls obj->as_parameter() to convert from Python to C, but of course
this gives you no typechecks as your O@ proposal does.

I've reread your original O@ proposal, and I like it very much.
Aren't there really any other positive responses?
