Used Use
++++++++

  This rule lists the ``use`` statements. Those ``use`` are made to import namespaces structures, including functions and constants, and not to include traits in classes.

.. code-block:: php
   
   <?php
   
   namespace A {
       class b {}
   }
   
   namespace B {
       use A\B as B;
       
       new B();
   }
   
   ?>
