- specs/slots are (usually) constant & static; pointers to types are not always C constant expressions (on Windows, if they come from a different DLL)
- specs/slots are (usually) shared across all subinterpreters; types are specific to a single interpreter

It's better to pass the metaclass as a function argument, as with bases. I'd prefer adding a new function that using a slot.
