Committee Fireside Chat
summary
Panel lays out concrete progress and tradeoffs: modules in C++20 already remove many include-guard problems; reflection and generation are the linchpins that make metaclasses roughly “95%” achievable; C++23 targets more compile-time features and a modules ecosystem TR (sg-15) to ease build/packaging interop; practical wins include no_unique_address, container::contains, spaceship, and lambda template syntax. Migration relies on tools—clang tools, clang-tidy, sanitizers, vcpkg/Conan—and the committee stresses avoiding ABI-breaking churn while exploring “editions” for opt-in, staged changes.
