PHP 7.2 Scalar Typehints
++++++++++++++++++++++++

  A new scalar typehint was introduced : object. 

It can't be used before PHP 7.2, and will be confused with classes or interfaces.

.. code-block:: php
   
   <?php
   
   function test(object $obj) : object
   {
       return new SplQueue();
   }
   
   test(new StdClass());
   
   ?>
