frame_graph's FG_DEPS

[Nielsbishere]

Is your request related to a problem? Please describe.
FG_DEPS doesn't allow infinite expansion (only up to 6 dependencies) and requires the end-user to specify number of dependencies; which is redundant if using templates instead.

Describe the solution you'd like

fg_dep<DeferredMainTaskData, RTHybridData>();

where fg_dep:

namespace fg_deps
{
	using type = std::vector<std::reference_wrapper<const std::type_info>>;

	template<typename T, typename ...args>
	struct insert
	{
		static inline void exec(type& deps)
		{
			deps.push_back(typeid(T));
			fg_deps::insert<args...>::exec(deps);
		}
	};

	template<typename T>
	struct insert<T>
	{
		static inline void exec(type& deps)
		{
			deps.push_back(typeid(T));
		}
	};

	template<typename ...args>
	static inline type make() {
		type result;
		insert<args...>::exec(result);
		return result;
	}

}

template<typename ...args>
static const fg_deps::type& fg_dep()
{
	static fg_deps::type deps = fg_deps::make<args...>();
	return deps;
}

Describe alternatives you've considered

My solution to this was just:

template<class ...Ts>
std::vector<std::reference_wrapper<const std::type_info>> Deps() {
    return { (typeid(Ts))...};
}

Yeah that's way cleaner, I didn't know this was a way of calling functions with variadic arguments. Only used sizeof...() before; which is different.
