Careful where you store that ref. If you're using process-global space,
you've just broken loading your library into multiple Lua states in the
same process.
Excellent point... for my purpose I'm not building a generic module and there is only one Lua state. For creating a generic module, using upvalues seems to be the best way to improve performance of type checking.
