title: How to inherit a pseudo-class properties?
body: <p>I have a class that "extends" a class. I want it to also automatically extend "related pseudo-classes". What I mean by that:</p>
  
  <p>Original class is</p>
  
  <pre><code>.original {
     property1: foo;
     &amp;: before {
        property2: bar;
     }
  }
  </code></pre>
  
  <p>New class is</p>
  
  <pre><code>.inheriting {
     .original;
  }
  </code></pre>
  
  <p>I now want to <code>.inheriting: before</code> to have the same properties as <code>.original: before</code>. How do I do that in an easy way?</p>
