First impression of Scala

Even though generally speaking, I am against choosing symbolic programming over verbose and well-readable code, I have to admit that this code snippet taken from the Wikipedia entry on Scala is nothing short of beautiful:

def qsort(list: List[Int]): List[Int] = list match {
  case Nil => Nil
  case pivot :: tail => {
    val (smaller, rest) = tail.partition(_ < pivot)
    qsort(smaller) ::: pivot :: qsort(rest)
  }
}
