Message
The type of message being received,
which must be Any for akka.actor.Actor,
and must be the same type of T for akka.actor.typed.Behavior.

The above code creates an actor to echo any messages.
import akka.actor._
def echoActor = new Actor {
def receive: Receive = {
while (true) {
val lastMessage = !ReceiveMessage[Any]
sender() ! lastMessage
}
thrownew Exception("Unreachable code!")
}
}
val pinger = system.actorOf(Props(echoActor))
pinger ! "hello world"
expectMsg("hello world")
