Methods Without Return
++++++++++++++++++++++

  List of all the functions, closures, methods that have no explicit return. 

Functions with the ``void`` or ``never`` return types, are omitted.

.. code-block:: php
   
   <?php
   
   // With return null : Explicitly not returning
   function withExplicitReturn($a = 1) {
       $a++;
       return null;
   }
   
   // Without indication
   function withoutExplicitReturn($a = 1) {
       $a++;
   }
   
   // With return type void : Explicitly not returning
   function withExplicitReturnType($a = 1) : void {
       $a++;
   }
   
   ?>

Suggestions
___________

* Add the returntype 'void' to make this explicit behavior
