Enums four ways
summary
Compares four concrete ways to get enum names and values: a boost preprocessor macro list that builds a constexpr string array (works fast and at compile time but requires contiguous values); a pretty function parser with static recursion that extracts identifiers (compiler- and namespace-dependent and needs an explicit enum count); a set of typed static value objects with explicit assignments; and a compile-time counter trick that auto-increments but forbids mixing explicit values — all viable but imperfect.
