I *don't* think it's complicated (once you get used to metatypes).

I'm not sure we talk about the same thing: we (at least me) do not
want to serialize and reconstruct objects (what pickle does),
we want to convert objects from Python to C (convert them to parameters
usable in C API-calls), and back (convert them from handles, pointers,
whatever into Python objects) having only the Python *type* object
available in the latter case.
Or am I missing something?
