title: Angular evaluate variable name
body: <p>I have the following loop:</p>
  
  <pre><code>$scope.loop = ['loopone','looptwo'];
  
  $scope.loopone = {'one', 'two'};
  $scope.looptwo = {'three', 'four'};
  </code></pre>
  
  <p>and I'm looping through it here:</p>
  
  <pre><code>&lt;div ng-repeat="slug in loop"&gt;
    &lt;div ng-repeat="val in {{ slug }}"&gt;{{ val }}&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I evaluate the <code>{{ slug }}</code> inside the second <code>ng-repeat</code>?</p>
