title: parent, &, intercalation in css attribute
body: <p>I have the following code:</p>
  
  <pre><code>  &amp;__menu {
      float: left;
      list-style: none none;
      padding: $navbar-menu_padding;
      [class^=#{&amp;}__item] { 
      ....
  }
  </code></pre>
  
  <p>I'm trying to an interpolation of <code>&amp; - [class^=#{&amp;}__item]</code>.</p>
  
  <p>This will fail, with or without interpolation. </p>
  
  <p>There is another option, besides writing the full name of the class ?</p>
