title: What's the point of calling next() after res.send() in Resitfy?
body: <p>I am familiar with Express but new to Restify. Restify's document has many examples calling <code>next()</code> after <code>res.send()</code> as below:</p>
  
  <pre><code>server.get('/echo/:name', function (req, res, next) {
    res.send(req.params);
    return next();
  });
  </code></pre>
  
  <p>This looks like a recommended pattern by some Restify experts as well:</p>

  <p>What's the real use case of doing this? After you call <code>res.send()</code>, is there anything a handler next in the chain can do?</p>
