title: point to class by reference
body: <p>My application has a number of identical AS3 class instances:</p>
  
  <pre><code>var Pan1:Panel = new Panel(etc);
  var Pan2:Panel = new Panel(etc);
  var Pan3:Panel = new Panel(etc);
  var Pan4:Panel = new Panel(etc);
  </code></pre>
  
  <p>One of these instances is manipulated at a time. I'd like to refer to this 'active' instance like:</p>
  
  <pre><code>var ActivePanel:Panel = Pan3;
  </code></pre>
  
  <p>But in such a way, that when I change: <code>ActivePanel.property1</code>, this also automatically changes the original instance (i.e. <code>Pan3.property1</code>).</p>
  
  <p>I've searched Google for an answer, but I guess with the wrong query... Can anyone please point out how to do this?</p>
  
  <p>Thanks a lot!</p>
