This quashes a new warning in clang++ 15, when std::move() (the one-parameter version) is used as simply move(). There is a strong recommendation from WG21 to avoid that. Details here: https://reviews.llvm.org/D119670 It might be that we should not use that many move()s. I am not competent to decide on that. I also used this occasion to get rid of a spacial casing for C++11 that does not seem necessary after all.
