title: what is the type of a template referance variable passed as input?
body: <p>I do have following piece of (pseudo-) code</p>
  <pre class="lang-html prettyprint-override"><code>&lt;some-component   #someComponent/&gt;
  
  &lt;another-component [reference]=&quot;someComponent&quot; /&gt;
  </code></pre>
  <pre class="lang-js prettyprint-override"><code>@Component(...)
  export class AnotherComponent {
   @Input() reference     // &lt;--- type
  }
  </code></pre>
  <p>My question now is: What is the type of the <code>Input</code> <code>reference</code>? I did not find anything in the docs. It is (as far as I can say) not an <code>ElementRef</code>. I do then want to access the <code>nativeElement</code> of the passed <code>reference</code>.</p>
