Micro Common Flavors

摘要

A new Flavors system is described. The basic features of the old Flavors system are retained. New issues concerning the inheritance mechanisms are, however, taken into account and a new algorithm is proposed which is much closer to an interpretation of inheritance allowing a formal, non-monotonic logical semantics for the overriding of attribute defaults. Further, a metaclass concept is introduced (flavors are objects too). Multiple inheritance for class specification is possible for both the object level (rooting in the standard class OBJECT) and the meta level (rooting in CLASS, the class of all classes).
