Hmmm… this is a feature though. There is nothing wrong with accessing a key which doesn't exist. Table access has nothing to say about 'safety'.
On the other hand… are you a Python person perhaps? Looking for something like KeyError? If so, it's trivial to implement your own.
So, as mentioned, feel free to shape your own Lua whichever way you see fit.
