Sorry, the move constructor isn't necessary...

template<typename _Tp, _Tp __v>
struct integral_constant {
  constexpr integral_constant(const integral_constant&) noexcept {}
  constexpr integral_constant() noexcept {}
};

int main() {
  auto l = [](auto value) {
    constexpr auto i = value;
    static_cast<void>(i);
  };
  l(integral_constant<unsigned, 0>{});
}
