To answer that question, I wrote a simple plugin which just dumps the names (which do not start with underscore) in std namespace (and its inlined namespaces) and for non-inline namespaces in there which do not start with underscore also recurses on those namespaces. Plugin source in https://gcc.gnu.org/pipermail/libstdc++/2025-August/062859.html I went through it all now, using cppreference as a quick check for stuff removed in C++17/C++20 and for everything added verified it is in corresponding eel.is/c++-draft/*.syn etc. and looked it up in the libstdc++ headers for guarding macros. 2025-08-04 Jakub Jelinek <ja...@redhat.com> hexne <print...@gmail.com> PR libstdc++/121373 * src/c++23/std.cc.in (std::ranges::shift_left, std::ranges::shift_right): Only export for C++23 and later.
