My guess is that when using a rest-param a call to next is involved thus realizing two elements of the sequence. A call to rest only realizes the first element:
user> (defn f [x] (println x) x) #'user/f user> (defn s [n] (lazy-seq (cons (f n) (s (inc n))))) #'user/s user> (def t (rest (s 0))) 0 #'user/t user> (def u (next (s 0))) 0 1 #'user/u -- You received this message because you are subscribed to the Google Groups "Clojure" group.
