title: Load HAML partial from another HAML file
body: <p>Is it possible in HAML to use haml in haml like templates? </p>
  
  <p>example: </p>
  
  <ul>
  <li>menu.haml</li>
  <li>layout.haml</li>
  <li>page1.haml</li>
  </ul>
  
  <p>page1 for example: </p>
  
  <pre><code>haml: menu.haml
  
  %p 
    content
  </code></pre>
  
  <p>as you know, get our layout from layout.haml (like a banner and such).
  I want to make a seperate menu part in a haml file. Is this even possible?</p>
