title: Sass partial importing
body: <p>I have an issue with sass compilation.</p>
  
  <p>When I have a project with a partial <code>_partial.scss</code> and have it imported in multiple partial files (because it contains color variables) it will end up in the compiled css multiple times!</p>
  
  <p>This is ugly because the same rule will 'overrule' itself multiple times which makes debugging info (chromium dev tools / firebug) rather unreadable.</p>
  
  <p>I presume there is a solution for all this. I just can't find anything on the issue, anywhere.</p>
