Ha! I just stumbled onto this recently to solve an ugly performance issue and it works great.
The cost is a layer of complexity added to the update function. In this way, the intermediate calculations need be done just once per update rather than spread out many times over the view. Well worth the effort to keep users oblivious to the difficulties and happy with the results. Perhaps there is a way to store such dependent state separately? Until then I shall keep this technique close to hand.
