title: SASS Variable within string
body: <p>Hi all I'm new to SASS (late I know) and playing around with mixins. </p>
  
  <p>Basically is there a way to link a variable to a string here is what I'm trying to do but it throws errors.
  (This is a condensed version)</p>
  
  <pre><code>@mixin post-link ($class, $color, $hover) {
      a.$class:link {
          color: $color;
      }
      a.$class:hover {
          color: $hover;
      }
  }
  </code></pre>
  
  <p>Link I say this is a little simpler than what I am trying to do in the mixin (more variables in full one).</p>
  
  <p>EDIT: should add i'm using Compass.
  Thanks</p>
