Reusable C++ Code, Reusable C++ Data Structures
summary
Shows how a real layout algorithm called vertical center example gets reused for widgets and rectangular bitmaps by refactoring to a templated function that operates on ranges of rectangles, uses minimal Concepts, and prefers function overloads, output functions or callable customization over heavy inheritance. Explains sharing code+state via CRTP or templated base classes, avoids heap and refcounting with intrusive lists, and warns how easy std::variant misuse can grow into an accidental polymorphic design that should have been a runtime-polymorphic value type.
