Code:
(def fib
(lazy-seq
(concat [0 1] (map + fib (rest fib)))))
(take 10 fib) ;; Bomb
Got the error message: _StackOverflowError clojure.lang.RT.more
(RT.java:589)_
And the following solutions works well:
(def fib
(concat [0 1] (lazy-seq (map + fib (rest fib))))) ;; Works well
(def fib
(lazy-cat [0 1] (map + fib (rest fib)))) ;; Works well
All of the above program using lazy-seq, why the first one rase
stackoverflow exception?
