There’s no laziness in that example. With laziness introduced by map, the caching done by lazy seq shows: user> (def foo (int-array [1 2 2 5 9 3])) #'user/foo user> (def baz (map identity foo)) #'user/baz user> baz (1 2 2 5 9 3) user> (aset foo 3 3) 3 user> baz (1 2 2 5 9 3) —Steve -- You received this message because you are subscribed to the Google Groups "Clojure" group.
