Lightning Talk: Cute Approach for Polymorphism in C++
summary
Claims a concrete pattern: replace per-element virtual calls with one virtual call per vector by making the virtual method take a span of many elements, implement per-element work in a nonvirtual method, and provide a CRTP-style templated handler layer that iterates the span and calls the derived per-element routine. Compares to a Concepts+variant approach that forces recompiles, targets millions/billions of items, and reports restored bandwidth and encapsulation with minimal runtime overhead.
