I'd argue it shouldn't (empty? (cycle [1 2 3])) => false (zero? (count (cycle [1 2 3]))) ... infinite loop This is also a problem for finite seqs, where count is a O(n) operation. With that in mind, the single seq object allocated by empty? doesn't seem so bad. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
