title: Sass mixin to apply to class
body: <p>The following Sass:</p>
  
  <pre><code>@mixin colourCount
    .one
      background: rgba(0, 160, 0, 0.5)
    .two
      background: rgba(255, 255, 0, 0.6)
  
  .count
    @include colourCount
  
  .cost
    @include colourCount
  </code></pre>
  
  <p>Produces the CSS:</p>
  
  <pre><code>.count .one {
    background: rgba(0, 160, 0, 0.5);
  }
  .count .two {
    background: rgba(255, 255, 0, 0.6);
  }
  
  .cost .one {
    background: rgba(0, 160, 0, 0.5);
  }
  .cost .two {
    background: rgba(255, 255, 0, 0.6);
  }
  </code></pre>
  
  <p>Is it possible with Sass to reuse the mixin to produce, notice the absence of a space between <code>.cost</code> and <code>.one</code>:</p>
  
  <pre><code>.count .one {
    background: rgba(0, 160, 0, 0.5);
  }
  .count .two {
    background: rgba(255, 255, 0, 0.6);
  }
  
  .cost.one {
    background: rgba(0, 160, 0, 0.5);
  }
  .cost.two {
    background: rgba(255, 255, 0, 0.6);
  }
  </code></pre>
  
  <p>Something like:</p>
  
  <pre><code>.cost @include colourCount
  </code></pre>
  
  <p>would be great but obviously doesn't work.  Is this possible at all?</p>
