Idiomatic Moonscript code (if that exists) is probably more
functional and "clever" than Lua. But I am not sure that this
is always a net win.

For instance, take this. Can you guess what this does?

Yes, this is clever. And error-prone:

I would almost always rather have slightly longer, boring but
straightforward Lua code.
