On the benefits of non-intrusiveness
summary
Compares intrusive OOP (public inheritance, interfaces) with non‑intrusive C++ techniques and shows concrete recipes: using traits and std::numeric_limits to expose a type’s max value without changing existing types, a void_t‑based detection pattern to test whether expressions compile, and C++20 concepts to require “addable” or “incrementable” types at compile time. Contrasts those with C# constraints and extension methods, explains refactoring and compile‑time costs, and demonstrates wrappers/variant approaches that work without modifying original classes.
