DynaMix: A New Take on Polymorphism in C++
summary
A C++ library that actually composes and mutates objects at runtime: objects, dynamic mixins, and unicast/multicast messages form the API, with mixins registering global-function–style messages rather than using CRTP or a huge virtual base. Demo builds a dragon, adds and removes hostile AI and player-controller mixins on the fly, and calls act to show behavior swaps. Priorities let one mixin override unicast handlers; multicast runs all implementers. Hosted on GitHub.
