Duplicate Enum Case Value
+++++++++++++++++++++++++

  In a backed enumeration, may it be ``int`` or ``string``, the values of the cases must all be distinct. There can't be two of them of the same value.

.. code-block:: php
   
   <?php
   
   enum e: int {
   	case A = 1 + 1;
   	case B = 2;
   }
   
   enum e2: string {
   	case A = 'A';
   	case B = 'A';
   }
   
   ?>
