Free your functions!
summary
Claims that C++ should favor non-member non-friend functions over member functions and backs that with concrete examples and mechanisms: a small reset_values free function reduces coupling and duplication, enables overloading and templates, and makes unit testing simpler; standard-library moves like std::begin and free real/imag show generic-code necessity; a struct-with-member compute example demonstrates performance limits (thispointer inhibits optimization) and a free function can be faster. Also covers namespaces, detail hiding, and mock/virtual dispatch patterns.
