title: Angular2 routerLink fragment with variable
body: <p>Is it possible to do something like:</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li *ngFor="let language of languages"&gt;
          &lt;a [routerLink]="['#' + language]"&gt;{{language}}&lt;/a&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li *ngFor="let language of languages"&gt;
          &lt;a fragment="language"&gt;{{language}}&lt;/a&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>to keep the same <code>url</code> and add <code>#en</code>, <code>#es</code> or <code>#fr</code> depending on what <code>language</code> value is? I can't make it work.</p>
