The __call metamethod must be a plain function, you can't pass
arbitrary callable objects (such as an FFI function). I don't see
an easy way to work around this -- it would require double
dispatching (or many more dispatches in the worst case).

Umm, examples? E.g. __add can certainly be an FFI function.
