Classes C++23 Style
summary
Summary of concrete takeaways: prefer rule of zero for simple value types and implement the rule of five only when managing memory; build small resource wrappers that are deliberately move-only (example: a file wrapper that moves correctly) and use the new move-only function to hold callbacks; make as many APIs constexpr/constinit as possible and exploit transient compile-time allocations for validation; specialize std::formatter for types to enable std::print and use deducing this to replace cumbersome ref-qualified accessor overloads.
