The hidden rules of world-class C++ code
summary
Claim: the familiar factory method can be reimplemented without heavy inheritance while keeping delegation, extensibility, reuse and runtime selection. Demonstrates working code (repo: https://github.com/BorisSchaeling/worldclasscode) and compiles examples that swap virtual dispatch for std::function and Boost.TypeErasure or for templates and factory functions, returning unique_ptr where needed. Shows when runtime polymorphism is necessary, when type erasure or free functions are clearer, and that the alternate implementations actually build and run, with tradeoffs in scope, clarity and performance measured by practical examples.
