It is actually the reverse: if the theory does not explain facts, it is wrong. Ada's subtype as defined by RM is a fact to explain (and to predict consequences of the choices made). The theory does it quite well. The rant about how Ada's RM names its subtypes is absolutely irrelevant. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
