title: Regex to match all scala keywords in a file
body: <p>Is it possible to build a regexp to match all keywords in a scala source file?</p>
  
  <p>The best I came with so far:</p>
  
  <pre><code>"""(?&lt;![\w`])(%s)(?![\w\_])""" format keyword
  </code></pre>
  
  <p>Is this good enough or I missed something?</p>
