Yes; I'm not sure why but the lazy-seq version is significantly faster than iterate, though the latter is interesting from a theoretical functional-programming perspective. All the boxing and unboxing (destructuring) on each iteration probably account for the difference. The iterate version, mind you, doesn't blow up if the finite input seq with the smallest maximum value isn't also the first. :) user=> (equal-values [[3 7 11] (range 5)]) (3#<BOOM! java.lang.NullPointerException> (But the fix to that bug is easy to apply to both other versions and doesn't appreciably slow them down.) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
