title: list.reverse() is not working
body: <p>I honestly just don't understand why this is returning <code>None</code> rather than a reversed list:</p>
  
  <pre><code>&gt;&gt;&gt; l = range(10)
  &gt;&gt;&gt; print l
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  &gt;&gt;&gt; print l.reverse()
  None
  </code></pre>
  
  <p>Why is this happening?  According to <a href="http://docs.python.org/2/tutorial/datastructures.html#more-on-lists">the docs</a>, I am doing nothing wrong.</p>
