--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is slightly more reduced:
constexpr bool use_func_v{};
struct func_obj
{
    template<class T> requires use_func_v
    void operator()(T);
};
template <typename t, typename ...args>
concept tt = requires {t{}(args{}...);};
constexpr bool bar{tt<func_obj, char>};
