   Example:

   1. This ReceiveMessage.Partial keyword can be used in the akka.actor.Actor.Receive domain, to receive the next message that is a Message. The above code creates an actor to echo any string messages.

      import akka.actor._
      def echoActor = new Actor {
        def receive: Receive = {
          while (true) {
            val lastMessage = !ReceiveMessage.Partial[String]
            sender() ! lastMessage
          }
          throw new Exception("Unreachable code!")
        }
      }
      
      val pinger = system.actorOf(Props(echoActor))
      pinger ! "hello world"
      expectMsg("hello world")

      All messages that are not the class of Message will not be handled.

      object UnhandledMessage
      pinger ! UnhandledMessage
      pinger ! "string message"
      expectMsg("string message")
