/**
 * Loads string templates, also known as inline templates.

 * This loader is intended to be used in a Twig loader chain and whitelists
 * string templates that begin with the following comment:
 * @code
 * {# inline_template_start #}
 * @endcode
 *
 * This class override ensures that the string loader behaves as expected in
 * the loader chain. If Twig's string loader is used as is, any string (even a
 * reference to a file-based Twig template) is treated as a valid template and
 * is rendered instead of a \Twig_Error_Loader exception being thrown.
