Another fix to avoid extra-copying ...

	template <class I, class V>
	void iter_set(I& t, V&& v)
	{
		*t = std::forward<V>(v);
	}
	
	template <class I, class V, typename... Args>
	void iter_set(I& t, V&& v, Args&& ...args)
	{
		*t++ = std::forward<V>(v);
		iter_set(t, std::forward<Args>(args)...);
	}
	
	template <class C, typename... Args>
	C gather(Args&& ...args)
	{
		C x;
		x.SetCount(sizeof...(args));
		auto iter = x.Begin();
		iter_set(iter, std::forward<Args>(args)...);
		return x;
	}
