nums = Stream.iterate(1, &(&1 + 1))
fizz = Stream.cycle ["", "", "Fizz"]
buzz = Stream.cycle ["", "", "", "", "Buzz"]
fizzbuzz = Stream.zip(fizz, buzz) |> Stream.zip(nums) |> Stream.map(fn
  {{"",       ""      },  number} -> number
  {{fizzword, buzzword}, _number} -> fizzword <> buzzword
end)
fizzbuzz |> Stream.take(100) |> Enum.each(&IO.puts/1)

this is pretty cool.
