Member sparta::OneWayBool< Default >::set_DEPRECATED (bool b): This should not be used. It is a temporary fix for AssignOnceObject's unassign_DEPRECATED function which has its own dependency.
Member THROW_IF_NOT_UNWINDING (exclass, msg_construct): this should not be used because std::uncaught_exception() can not fully prevent ending up in a double-exception case as explained in https://akrzemi1.wordpress.com/2011/09/21/destructors-that-throw/
