Variadic template function to make a hash using std::hash and combining them

makeHash.cpp

// recursive variadic template hash
// base case
template<typename T>
std::size_t makeHash(const T& v)
{
	return std::hash<T>()(v);
}

// recursive variadic template hash
template<typename T, typename... Args>
std::size_t makeHash(T first, Args ... args)
{
	//auto n = sizeof...(Args);
	std::size_t h = std::hash<T>()(first) ^ (makeHash(args...) << 1);
	return h;
}

Very useful resource, thank you!
