title: RegEx Quickie Special Selection
body: <p>Alright, I'm no pro at RegExpression so can someone give me the reg expression that would select the <code>display()</code> and <code>first_name</code> in the following haystack string?:</p>
  
  <pre>
  <code>
  $Question -> display();
  $Person -> first_name;
  </code>
  
  </pre>
