Yes, but the metatable for the type is stored in the registry and I
thought that was only accessible from the C API.
So in lua I can get the metatable for the object I want to test with
getmetatable, but I cant see a way to get the metatable for the type
from the registry in order to do the comparison.

I guess it is not a major issue since I can implement something based on
luaL_checkudata pretty simply. I just didn't want to fall into the habit
of writing C API functions for things that can actually be done in lua
