I did something similar using (iterate rest coll), which I called iter- rest:
(defn iter-rest "Takes the first (count coll) items from call to (iterate rest coll). If passed function as first argument, calls it on each invocation of rest, i.e. (iterate #(func (rest %)) coll)." ([coll] (take (count coll) (iterate rest coll))) ([func coll] (take (count coll) (iterate #(func (rest %)) coll)))) user=> (iter-rest (range 3)) ((0 1 2) (1 2) (2)) I now realize a key difference is that, by using (count coll), iter- rest fully realizes anything lazy; for Andrew's lazy version above, I second the name "rests."
