First, you've clearly missed something here because this is not https://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#2237 . Note carefully that the above link that you provided was for declarations of ctors and dtors inside the class definition itself and not for declarations at namespace scope. Second, i'm already aware that this is rejected by gcc with c++20 as i provided a demo link https://godbolt.org/z/TYjEzss6q at the first line of my bug report.
