Well, I cannot do anything about that, either way, mate.

Just use different Lua states.

What's so bad about that?

Not if you set new global tables for the child states and make those
global tables inherit from the main state. Setting a __metatable field
in the metatable of the child state global table should protect the
parent global table for any access from Lua.
