Yes, you are right, it is available in GCC 12 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100977).

Since it is a C++23 feature, can we at least have it only if the user requests C++23 standard compliance? Isn't it strange to force it upon users if they specify `-std=c++20`? I am going to check how GCC 12 behaves with this regard.
