mystring[3] is a very common gotcha for Lua newbies.

However I'm not sure it may be used as an excuse for low-level language changes.

I'm for a metatable on string module's table — to catch __index and
__newindex access and fail with meaningful runtime error.

This is cheap and, unless I'm missing something, should solve the problem.
