Не работает в MSVC17 operator == и operator !=

[XRay3D]

main.cpp:82: ошибка: C2593: неоднозначный "operator =="
main.cpp:19: может быть
bool operator ==<int,double,char>(type_pack<int,double,char>,type_pack<int,double,char>)
main.cpp:17: или
bool operator ==<int,double,char,int,double,char>(type_pack<int,double,char>,type_pack<int,double,char>)
main.cpp:83: при попытке сопоставить список аргументов
(type_pack<int,double,char>, type_pack<int,double,char>)

Я решил так.
template <class... Ts, class... Us, class T = disable_if_t<std::is_same_v<Ts..., Us...>>>
constexpr bool operator==(type_pack<Ts...>, type_pack<Us...>) { return false; }
