Meta Polymorphism
summary
Claim: C++ offers many kinds of polymorphism beyond virtual functions, and the talk demonstrates concrete techniques that work. It shows polymorphism at pre-processing compilation link and runtime, macros (mccarran) for compile-time hooks, templates and explicit instantiation with a “Chinese wall” for tests, link-time mocking with fcm, visitor and registry maps to emulate multiple dispatch, and value-semantics type‑erasure using any + lambda to avoid heap allocations — each described with code patterns and when they succeed or cost you.
