Example

Unlike Function.unlift, this UnliftOps.unlift method can be used in extractors.

val of: Int => Option[String] = { i =>
  if (i == 2) {
    Some("matched by an optional function")
  } else {
    None
  }
}
util.Random.nextInt(4) match {
  case of.unlift(m) => // Convert an optional function to a pattern
    println(m)
  case _ =>
    println("Not matched")
}
