That is a concern. Really the only thing I want to persist across script
scans is the registry. Everything else can be reinitialized.

I don't understand what the line
     lua_rawgeti(L, LUA_REGISTRYINDEX, errfunc); // index 1
does. It pushes error_function on the stack, but then what? It doesn't
seem to do anything with it. Is this maybe some old code that didn't get
updated or do I just not understand?
