6    Support for the ``__toString()`` magic method has been added in Twig 2.3.

8The ``length`` filter returns the number of items of a sequence or mapping, or
9the length of a string.

11For objects that implement the ``Countable`` interface, ``length`` will use the
12return value of the ``count()`` method.
13
14For objects that implement the ``__toString()`` magic method (and not ``Countable``),
15it will return the length of the string provided by that method.
16
17For objects that implement the ``Traversable`` interface, ``length`` will use the return value of the ``iterator_count()`` method.
