title: Stylus: store variables in an object
body: <p>I have the following object/hash for example:</p>
  
  <pre><code>$colors = {
     black: #000,
     gray: #666
  }
  </code></pre>
  
  <p>When I try and do something like this, I get an <code>expected "indent", got "outdent"</code> error. </p>
  
  <pre><code>body
      background-color $colors.gray
  </code></pre>
  
  <p>Is there a way to do something like this? I think its just easier to read.</p>
