title: Akka: What happens when you tell an ActorRef and it expects you to ask?
body: <p>I have the following:</p>
  
  <p><code>val future = myActor ? Message</code></p>
  
  <p>And in my actor my receive message has something like this:</p>
  
  <p><code>sender ! Response</code></p>
  
  <p>If I do the following and ignore the response, is there any negative impact?</p>
  
  <p><code>myActor ! Message</code></p>
  
  <p>Maybe I'm just missing where it says this in the documentation.  Is it like a method that returns a value and the caller doesn't assign the return value to anything?  If I make that call from another actor is there going to be some weird threading issue or memory leaks that result from it?  My unit tests don't seem to be affected but it's kind of a contrived.  I'm hoping I'm just over-thinking the problem and maybe I can't find the answer because it's a stupid question that no one in their right mind asks.</p>
