An object model for dynamic mixins

摘要

Dynamic mixins allow objects to be modified at runtime with modular extensions. In applications where method calls must traverse through multiple extensions, a performance penalty relative to static inheritance is realized as receivers of super-calls must be determined at run-time. This work describes an object model which significantly reduces this penalty. The approach is described in terms of a statically typed dynamic mixin-based language called nix. (C) 2017 Elsevier Ltd.
