This is the solution to a useless interview problem.

fizzugh.scala

// fizzbuzz in 116 chars
(1 to 100)map{n=>val v=Seq(3->"fizz",5->"buzz").collect{case(m,s)if n%m==0=>s}.mkString;if(v=="")n.toString else v}

// less cryptic version
val mods = Seq(3 -> "fizz", 5 -> "buzz")
(1 to 100).map { n =>
  val words = mods.collect {
    case (m, s) if n % m == 0 => s
  }
  val v = words.mkString()
  if (v == "") n.toString else v
}
