Final Traits Are Final
++++++++++++++++++++++

  A final method in a trait is also final when in its importing class. This means that the importing class may redefine it, but not the children.

.. code-block:: php
   
   <?php
   
   trait t {
   	final function FFinal() {}
   	final function FNotFinalInClass() {}
   	function FNotFinal() {}     // This is a normal method
   }
   
   class x {
   	use t;
   	
   	function FNotFinalInClass() {}
   
   }
   
   class y extends x  {
   	function FFinal() {}            // This is KO, as it is final in the trait
   	function FNotFinalInClass() {}  // This is OK, the class as priority
   	function FNotFinal() {}   
   }
   ?>
