The popup text for indicates that prior to clang16 it was considered experimental and was disabled by default. It does not list 16 explicitly, however. https://releases.llvm.org/download.html does not even list clang16 yet: not officially released yet. https://libcxx.llvm.org/ReleaseNotes.html reports: "The C++20 ranges library has been completed and is no longer experimental. Some views have not been implemented yet. Work on C++23 ranges has started." https://libcxx.llvm.org/Status/Cxx20.html lists as "In Progress": "Views should not be required to be default constructible". It also indicates that status for "P2210R2 LWG Superior String Splitting", which is about split and such, see: https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2210r2.html ( https://libcxx.llvm.org/Status/Cxx20.html is in some ways more explicit than what cppreference.com lists. ) https://clang.llvm.org/cxx_status.html lists the compiler as only partially supporting C++20 as well. --=20 You are receiving this mail because: You are the assignee for the bug.=
