-   * ``type_params`` is a list of :ref:`type parameters <ast-type-params>`.
    * ``args`` is an :class:`arguments` node.
    * ``body`` is the list of nodes inside the function.
    * ``decorator_list`` is the list of decorators to be applied, stored outermost
      first (i.e. the first in the list will be applied last).
    * ``returns`` is the return annotation.
