This revision builds on the P2996 reflection framework and aims at attributes: reflecting standard (and some vendor) attribute syntax, comparing reflections, and wiring that into metaprogramming so generic code can see what is actually appertaining to an entity. If you follow constexpr metaprogramming or tooling-facing reflection, it is the thread starter for “what does [[...]] mean at compile time now?” The canonical redirect is https://wg21.link/p3385r7; if that flakes, use the 2026 mailing HTML on open-std.org the same way you always do.
