title: How do I get the nth item in a Queue?
body: <p>I have a number of queues and priority queues in my application. I would like to easily access the nth items in these queues, but don't see an easy way to do that using the API.</p>
  
  <p>I guess I could create an <code>Iterator</code> and iterate to the nth element or use <code>toArray()[index]</code>, but it seems like there should be an easier way. </p>
  
  <p>Am I missing something?</p>
