-Don't Use Annotations to Configure the Controller Template
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``@Template`` annotation is useful, but also involves some *magic*.
-Moreover, most of the time ``@Template`` is used without any parameters, which
-makes it more difficult to know which template is being rendered. It also hides
-the fact that a controller should always return a ``Response`` object.

-    There is no default listener inside the Symfony Framework for the ``kernel.view``
