title: Access current item in ng-repeat
body: <p>I have something like this:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;li ng-repeat="item in items"&gt;
      {{item.name}}
  &lt;/li&gt;
  </code></pre>
  
  <p>The <code>item</code> object has a property called <code>index</code>. How do I assign it to the <code>tabIndex</code> so my output looks like:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;li tabIndex="100"&gt;Mike&lt;/li&gt;
  &lt;li tabIndex="101"&gt;Smith&lt;/li&gt;
  </code></pre>
  
  <p>I've tried this but it cannot access the current item:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;li ng-repeat="item in items" tabIndex="item.index"&gt;
      {{item.name}}
  &lt;/li&gt;
  </code></pre>
