just a short question:

i noticed that all containers dont return a ref on the item created inside a container, when a copy Add is used: (here Array is example)

	T&       Add();
	void     Add(const T& x); //why void?
	void     AddPick(pick_ T& x); //why void?
	T&       Add(T *newt);

Mostly because of standard usage pattern...

It might be a little bit confusing as those variants that are taking parameter make a copy of this parameter (and would return a reference to this copy).

Also note the existence of Top() - only one more line...

But I am not strongly opposed to changing this either....
