A neat little solution for FizzBuzz in Scala

FizzBuzzer.scala

object FizzBuzzer {
  
  def process(i: Int) = i match {
    case a if contains("3")(a) => "lucky"
    case a if multiple(15)(a) => "fizzbuzz"
    case a if multiple(5)(a) => "buzz"
    case a if multiple(3)(a) => "fizz"
    case _ => i.toString
  }

  def contains(s: String)(a: Int) = a.toString.contains(s)

  def multiple(m: Int)(i: Int) = i % m == 0

  def doIt(r: Range): String = r.map(process).mkString(" ")

  println(doIt(1 to 20))
  
}
