If the functions were: (defn f [x] (g x)) (defn g [x] (f x)) They would operate in constant space with tail-call optimization. (defn f [x] (cons x (g x))) (defn g [x] (cons x (f x))) Will run out of memory even in languages that support tail call optimization. (assuming we're evaluating them eagerly) Lazy-seq's are often handy in Clojure to subvert the stack limit imposed by the the JVM, but it's not quite the same problem that TCO solves. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
