The Pipe |> Operator
How to implement and why to use the pipe operator
There is a "val" missing in the video - here's the correct implementation of the operator:
implicit class Pipe[T](val v: T) extends AnyVal {
def |>[U] (f: T => U) = f(v)
// Additional suggestions:
def $$[U](f: T => U): T = {f(v); v}
def #!(str: String = ""): T = {println(str + v); v}
}
