将mixin动态添加到actor的语法

Question

我有一个演员向另一个演员发送消息。它还创建了另一个actor，并且在编译时不知道它的类型。在创建时，它需要添加一个mixin。我想知道如何在语法上解决这个问题。例如，如果我们有：

trait MyMixin extends Actor {

  abstract override def receive = {

        case msg => 
            // Do something
            super.receive(msg)
    }
}

class Sender(targetClass: Class) extends Actor {

  // Here I want to create the actor such that I can add the mixin
  // eg. If I knew the class at compile time I could do the following: 
  // val target = context.actorOf(Props(new TargetActor with MyMixin))
  val target = context.actorOf(Props(???))

  target ! someMsg
  ...
}

所以问题是如何将这两个类组合起来进行运行时创建？
