Minimal FizzBuzz implementation in Scala

FizzBuzz.scala

package org.scalabound.scatdd

object FizzBuzz {
  
  def eval(x: Int) = (x % 3, x % 5, x) match {
    case(0, 0, _) => "FizzBuzz"
    case(0, _, _) => "Fizz"
    case(_, 0, _) => "Buzz"
    case _ => "" + x
  }

}

You don't need x in the tuple as well, you have access to it from the function's parameter. Would work with just a tuple of (x % 3, x % 5) :)
