Abstract
One of the main characteristics of classical class-based languages is the strict correlation between inheritance, subclassing, and subtyping. A great economy of concepts and syntax is achieved by identifying these three relations. The identification also confers much flexibility in the use of subsumption: an object of a subclass, some of whose methods may have been inherited, can always be used in place of an object of a superclass by virtue of subtyping.
