Object-oriented languages with multiple inheritance and automatic conflict resolution typically use a linearization of superclasses to determine which version of a property to inherit when several superclasses provide definitions. Recent work has defined several desirable characteristics for linearizations, the most important being monotonicity, which prohibits inherited properties from skipping over direct superclasses. Combined with Dylan's sealing mechanism, a monotonic linearization enables some compile-time method selection that would otherwise be impossible in the absence of a closed-world assumption.The Dylan linearization is monotonic, easily described, strictly observes local precedence order, and produces the same ordering as CLOS when that is monotonic. We present an implementation based on merging and a survey of class heterarchies from several large programs, analyzing where commonly used linearizations differ.

This paper describes Symbolics' newly redesigned object-oriented programming system, Flavors. Flavors encourages program modularity, eases the development of large, complex programs, and provides high efficiency at run time. Flavors is integrated into Lisp and the Symbolics program development environment. This paper describes the philosophy and some of the major characteristics of Symbolics' Flavors and shows how the above goals are addressed. Full details of Flavors are left to the programmers' manual, Reference Guide to Symbolics Common Lisp. (5)
