--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- Now that we have [[no_unique_address]] I'll make our std::tuple use it (I think I have a partial implementation in a local branch, that I couldn't compile when I started work on it). I don't plan to work on it until stage 3 though, as this is a bug and so fixing it is valid for stage 3.
