title: Kohana 3.2 + Twig Issues
body: <p>I'm using <a href="https://github.com/jheathco/kohana-twig/" rel="nofollow">this</a> module to integrate Twig into my small Kohana project. I'm facing the following issues:  </p>
  
  <ol>
  <li>How to use helpers/custom functions?  </li>
  <li>How to use Kohana core functions, ex. <code>__()</code> for translating, functions to create URLs?</li>
  </ol>
  
  <p>If anybody has any suggestions, I'd be delighted.</p>
