Note that loading (maliciously crafted) bytecode is generally not safe in Lua; sandboxing can be escaped in more ways than what's possible when loading plaintext sourcecode, and there are no full mitigations for this currently as far as I know (and would probably be highly interpreter/version sensitive anyway)-- the only "real" mitigation strategy is to just not `load` bytecode at all.

But this is probably a non-issue for a lot of usecases.
