title: Play Json - Compare nested Json-Array with Specs2
body: <p>With Play-Json and Specs2 I can match json-bodies like this:</p>
  
  <pre><code>contentAsJson(res) must equalTo(responseBody)
  </code></pre>
  
  <p>Is there a possiblity to ignore order (recursively) for json-arrays and instead treat equality for json-arrays like they were sets?</p>
