title: Mustache render list if not empty
body: <p>I would like to use Moustache to render an HTML unordered list only if a list object is not empty. So I would like:</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li&gt;item 1&lt;/li&gt;
      &lt;li&gt;item 2&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>if the list has elements and <em>nothing</em> if the list is empty (not even ul tags)</p>
  
  <p>How can I do this?</p>
  
  <p>edit: my data structure is:</p>
  
  <pre><code>{ "list": ["first item", "second item"] }
  </code></pre>
