title: What to return after $response->send() in Symfony2 controller?
body: <p>If I prepare a response in my controller like so:</p>
  
  <pre><code>$response = new Response();
  $response-&gt;setContent($this-&gt;render('mytemplate.html.twig');
  $response-&gt;send();
  </code></pre>
  
  <p>Rather than using:</p>
  
  <pre><code>return $this-&gt;return('mytemplate.html.twig');
  </code></pre>
  
  <p>Then I haven't actually returned anything... what should I do after $response->send()? Should I just return true?</p>
