Let's FizzBuzz in Haskell with HSpec.
multiples of 3 -> fizz : green
multiples of 5 -> buzz : red
multiples of 5 -> buzz : green
reordered if to guard : blue
multiples of 15 -> fizzbuzz : red
multiples of 15 -> fizzbuzz : green
no multiples of 3 or 5 -> n : red
no multiples of 3 or 5 -> n : green
touchdown. this was a real nice one.
