Interestingly, the committee is now discussing a proposal to make std::queue
constexpr, and it came up that no standard container can ever be used with a
constexpr std::queue, because no standard container can have a constexpr

However, it seems to me that both a "ring deque" and a vector-deque as in
DoubleEnded can provide a constexpr pop_front (in C++20.)

This might or might not be a sufficient reason to pursue these.
