title: Are "public slots:" sections still necessary in Qt5?
body: <p>A simple question regarding the new <em>signal/slot</em> syntax in Qt5:</p>
  
  <ul>
  <li>Are there still benefits for a <code>Q_OBJECT</code>-derived class to have <code>public slots:</code>sections declared?</li>
  </ul>
  
  <p>Note: With the new syntax you're able to connect a signal to <strong>any</strong> public function of a class or directly implement a C++11 lambda (which can also call some member functions itself).</p>
