body: <p>Is there a way to use variables in less <code>~</code> operator, like</p>
  
  <pre><code>~"calc(70% - @spacing)";
  </code></pre>
  
  <p>When I have tried it it only works with static values like</p>
  
  <pre><code> ~"calc(70% - 10px)";
  </code></pre>
  
  <p>Can I get the string to be evaluated prior to beeing set as a property. </p>
