The Object class currently does a direct comparison of the 'obj_name()' value of the thing being coerced, against the internal _obj_name field it was initialized with. This does not allow for creation of object fields which allow arbitrary subclasses - only the base class passes the check. Introduce a new 'subclasses' parameter, defaulting to False, which traverses the python class hierarchy, checking the obj_name() value on all parent classes of the value being coerced.
