``constant``
============
``constant`` returns the constant value for a given string:
.. code-block:: jinja
{{ some_date|date(constant('DATE_W3C')) }}
{{ constant('Namespace\\Classname::CONSTANT_NAME') }}
You can read constants from object instances as well:
.. code-block:: jinja
{{ constant('RSS', date) }}
Use the ``defined`` test to check if a constant is defined:
.. code-block:: jinja
{% if constant('SOME_CONST') is defined %}
...
{% endif %}
