"Prefixing" works pretty nicely, same as using the "local" keyword to create variables. This is much like in C. I have maintained quite a bit of Lua code and globals weren't a problem. If some code is doing something wrong regarding globals, you can use metatables to find the cause without much of a problem.
Don't try to make your engine bulletproof for people who don't understand what they do. They'll just break it differently and the more you try to prevent them from doing it, the more it'll hurt in the end. The earlier they are confronted with their own code that doesn't work, the better. That's my opinion at least.
