ActorDSL helps to provision actor to test in repl. For this example to work you need `build.sbt` file with akka dependency as stated here http://doc.akka.io/docs/akka/snapshot/intro/getting-started.html and type `sbt console` in same directory.

import akka.actor.ActorDSL._
import akka.actor.ActorSystem

// need an actor system, make it implicit to it's used by all our repl based actors
implicit val system = ActorSystem("demo")

// here's a simple example of creating an actor
// Also, this will give us a simple actor that is used to print the 
// results sent back to us from the other actors.
val a = actor(new Act {
  become {
    case msg => println(msg)
  }
})

// Now send the other actor something 
a ! "hi"
