How about the ternary operator?

  x ~= nil ? x : y

I bet you could do the above with the token filter ;-)

Or how about everything becomes an expression:

  tobeornottobe = if x == "B" then "be" else "be not" end

I like that in lua functions are first class objects. Very nice. But I
miss that control structures are not expressions, and that I can't break
to an arbitrary label.
