Yes. `string.find` is implemented in C. Invoking it (no matter how complex its arguments) requires just a few bytecode instructions.

Well, then that's library dependent and not an intrinsic part of the language. So shipping Lua safely would mean having to swap or drop parts of the standard library for something a bit more robust.

Apparently, that's what Lunatik does so the work seems to already have been done.

Appending strings together is a single bytecode instruction and this cannot really be fixed.
