``last``
========
The ``last`` filter returns the last "element" of a sequence, a mapping, or
a string:
.. code-block:: jinja
{{ [1, 2, 3, 4]|last }}
{# outputs 4 #}
{{ { a: 1, b: 2, c: 3, d: 4 }|last }}
{# outputs 4 #}
{{ '1234'|last }}
{# outputs 4 #}
.. note::
It also works with objects implementing the `Traversable`_ interface.
