template<typename>
struct dxle::type_traits::ignore_type< typename >

Trait class whose value is true regardless of what T is. we can use it, when we want to let SFINAE work for a decltype expressions.

template<typename T>
//return int
auto add(int a, T b)->std::enable_if_t<dxle::ignore_type<decltype(a + b)>::value, int>
{
    return a + b;
}

int main()
{
    add(0, 0);//OK
