well clang-12 was released 2 years ago ... I am trying to say that clang
already fixed this case for -std=3Dc++20 in a newer clang version and GCC s=
hould
fix this too, that is what PR 109551 is about.  Note compiler developers te=
nd
to try to the trunk (mainline) sources of each compiler to see if what other
compilers do and don't really look into older releases of the other compile=
r to
see when it was added especially when it comes to diagnostic improvments.=
