--- Comment #1 from Eric Estievenart <steve+gcc at tecwec dot eu> ---
Indeed, confirming with even simpler code ( https://godbolt.org/z/EPbsfxYcj ):

struct [[nodiscard]] Z {};

void f()
{
    Z{}; // should warn but does not
}

Tested all versions: 11.2, trunk, with -Wall -Wextra -....

This is really a need for modern code, even experienced developpers sometimes
forget the 'lock' in
Lock lock{&mutex};
and this has severe consequences ;-)
