For 0 being a FizzBuzz you can `cons` a "FizzBuzz" to the start of the list fizzbuzz = "FizzBuzz" : zipWith... To make negative numbers work you'd need a new numbers definition numbers = map show [-1, -2..] Should yield all the negative integers eventually. I've never heard of FizzBuzz defined for complex/imaginary/2-d numbers. That's interesting to consider, I'll be thinking about this for a while
