Description
___________
 
This error is emitted when a property is defined in an interface, with the final option. There, a property hook is automatically abstract, as it is part of an interface, so the ``abstract`` option is understated. 

In a class or a trait, the reported error is that ``abstract`` is not allowed on a property hook.

Example
_______

.. code-block:: php

   <?php
   
   interface I {
       public int $p {
           final get;
       }
   }
   
   ?>

Solutions
_________

+ Remove the ``final`` option from the property hook.
