Compile-Time Dispatch Evolved: C++23's Zero-Overhead Polymorphism

C++23's explicit object parameters unlock refined CRTP patterns that deliver compile-time polymorphism with zero runtime overhead, eliminating the vtable cost that plagues traditional virtual functions. This breakthrough is transformative for performance-critical systems where even microsecond-level optimizations matter. As static polymorphism gains first-class language support, developers can now choose compile-time dispatch without sacrificing code expressiveness.
