title: How to explicitly discard an out argument?
body: <p>I'm making a call:</p>
  
  <pre><code>myResult = MakeMyCall(inputParams, out messages);
  </code></pre>
  
  <p>but I don't actually care about the messages.  If it was an input parameter I didn't care about I'd just pass in a null.  If it was the return I didn't care about I'd just leave it off.  </p>
  
  <p>Is there a way to do something similar with an out, or do I need to declare a variable that I will then ignore?</p>
