FWIW, std::ranges in base libc++ 16 (via llvm-16-update branch) works fine at least in emulators/yuzu (c++20) and x11-wm/hyprland (c++23). More can take advantage but currently use a workaround e.g., $ rg -l :devel/range-v3 | sed s,/Makefile,, biology/seqan3 devel/fbthrift editors/imhex lang/solidity net-im/telegram-desktop
