title: Github - link to function in source
body: <p>I know I can have anchors to a certain line, but if the source changes that line might become irrelevant. Example:</p>
  
  <p><code>...source.php#L33</code> &lt; line 33 may become line 40 later :(</p>
  
  <p>Is there some way to tell GitHub to link to a certain function or property from the source, without specifying the line?</p>
  
  <p>(The source is written in PHP code.)</p>
