title: AngularJS access to $first of ngRepeat parent in a nested ngRepeat
body: <p>I'm trying to get access to $first of a ngRepeat parent from within a nested ngRepeat. Is there a way to alias or access $first for use within nested ngRepeat?  I've tried $parent.$first, but it doesn't appear to work.  Outputting to screen by interpolation indicates it has the same value as the $first of the nested child.</p>
  
  <pre><code>$parent.$first // same value as nested child
  </code></pre>
