Rule ``no_unreachable_default_argument_value``
==============================================

In function arguments there must not be arguments with default values before
non-default ones.

Warning
-------

Using this rule is risky
~~~~~~~~~~~~~~~~~~~~~~~~

Modifies the signature of functions; therefore risky when using systems (such as
some Symfony components) that rely on those (for example through reflection).

Examples
--------

Example #1
~~~~~~~~~~

.. code-block:: diff

   --- Original

    <?php
