Such a thing would surely be a very dangerous structure to have around. Clojure's approach is one of immutability and minimal global state, and a non-cached lazy seq would either have to generate the whole sequence up to the last value required every time it was accessed, or it would be creating a nasty implicit side effect in the var, as the seq would need to lose the new value each time it was accessed.
