Which return false. Then you have an abstraction layer which converts the false into an exception. Yes, in this simple use case it may be better to throw the exception directly. But as you begin to introduce these well-known design patterns there may appear some sense... Unset returns false if there was nothing to unset or if an unset_dimension/property handler has returned false. Short: It doesn't return true if nothing was successfully unset. Bob Weinand
