title: How to get an arbitrary element from a frozenset?
body: <p>I would like to get an element from a <code>frozenset</code> (without modifying it, of course, as <code>frozenset</code>s are immutable). The best solution I have found so far is:</p>
  
  <pre><code>s = frozenset(['a'])
  iter(s).next()
  </code></pre>
  
  <p>which returns, as expected:</p>
  
  <pre><code>'a'
  </code></pre>
  
  <p>In other words, is there any way of 'popping' an element from a <code>frozenset</code> without actually popping it?</p>
