 Interesting idea.  I'll check it out and see if this beats the string
compares with inlined setters and getters.

 I've also figured I can use lua_topointer() directly on the metatable to
check my userdata type instead of a registry lookup and a string compare
like luaL_checkudata() does.  This should be a big win for all my exported
functions.
