    A ``for`` loop. ``target`` holds the variable(s) the loop assigns to, as a
-   single :class:`Name`, :class:`Tuple` or :class:`List` node. ``iter`` holds
-   the item to be looped over, again as a single node. ``body`` and ``orelse``

-   loop finishes normally, rather than via a ``break`` statement.
