``empty``
=========
.. versionadded:: 2.3
Support for the ``__toString()`` magic method has been added in Twig 2.3.
``empty`` checks if a variable is an empty string, an empty array, an empty
hash, exactly ``false``, or exactly ``null``.
For objects that implement the ``Countable`` interface, ``empty`` will check the
return value of the ``count()`` method.
For objects that implement the ``__toString()`` magic method (and not ``Countable``),
it will check if an empty string is returned.
.. code-block:: jinja
{% if foo is empty %}
...
{% endif %}
