Got as far as this before my WTF moment: a != b let x = !(a >= b); let y = !(b >= a); x || y Also had pause to think at this: result = divide(5, 0) switch result[1] { case "": puts(result[0]) default: puts(result[1]) // prints "cannot divide by zero" } I mean... the language was looking pretty good up until that point.
