Use With Fully Qualified Name
+++++++++++++++++++++++++++++

  Use statement doesn't require a fully qualified name.

PHP manual recommends not to use fully qualified name (starting with \) when using the 'use' statement : they are "the leading backslash is unnecessary and not recommended, as import names must be fully qualified, and are not processed relative to the current namespace".

.. code-block:: php
   
   <?php
   
   // Recommended way to write a use statement.
   use  A\B\C\D as E;
   
   // No need to use the initial \
   use \A\B\C\D as F;
   
   ?>

Suggestions
___________

* Remove the initial \ in use expressions.
