Sure, that's by definition of sandbox, right? You *give* your *chosen*
execution environment. In your example, if you don't trust cheat, don't
add it to the environment.

In your example, I guess the best that could be done would be
to setfenv(g,B) for all Lua functions g in B. This can be done
automatically in a for loop in sandbox. Is this what you meant?
