small example for Pierre

function composition with implicit classes

val f: String => Int = (s  => s.length)

val g : Int => String = (i => i.toString)


implicit class Pipe[A,B](f : A => B) {
  def |>[C] (g : C => A) : C => B = f.compose(g)
}

implicit class Apply[A](a : A) {
  def |>[B] (fun : A => B) : B = fun(a)
}

4 |> (f |> g)
