There's a proposal for that https://open-std.org/JTC1/SC22/WG21/docs/papers/2020/p1040r6.html https://open-std.org/JTC1/SC22/WG21/docs/papers/2020/p1040r6... > non-fixed-sized containers, ie vector You can already use them in a constexpr context, you just can't leave it yet. So creating a vector on compile time and then using it on runtime is sadly not working right now but I think that's being worked on as well.
