--- Comment #2 from Pauli <suokkos at gmail dot com> --- Maybe this isn't exactly defect. But constexpr is hard beast to get right in any code. For user code simplest workaround would be remembering to use operator""sv everywhere. Too bad accessing those operator seems to be hard. I guess I need configure time check for that and provide my own fallback if the sv operator is missing.
