title: Is there any reason not to group class properties?
body: <p>I use docblocks to typehint class properties, and only recently realised that class properties may be grouped as such:</p>
  
  <pre><code>    /**
       * @var string
       */
      private $firstname, $surname, $location;
  </code></pre>
  
  <p>Which is way easier to read, and shorter, than this:</p>
  
  <pre><code>    /**
       * @var string
       */
      private $firstname;
  
      /**
       * @var string
       */
      private $surname;
  
      /**
       * @var string
       */
      private $location;
  </code></pre>
  
  <p>Would there be any reason not to do this?</p>
