This wouldn't be used by libraries, though: you'd have to modify them to
use it.

I'd like luaL_typerror (or luaL_typename) to try a __type metamethod.
Currently, I have to modify it, so "number expected, got table" can
become "number expected, got Sprite".

Maybe for number types, too, for custom number conversions.
