It's all yours. Really, just a slight change from your code anyway. I wonder about the call to next. I'm thinking it should be rest instead. (See http://clojure.org/lazy) I definitely don't like the way (flatten 10) and (flatten {:a 1 :b 2}) return the empty list (in 1.2 beta). I think these are accidents, and I worry that they will obscure higher-level bugs. My preference is to return the arg if it's not sequential? as I believe it will provide a more useful result at no extra cost. In that case, the argument to flatten was probably a mistake, and it's better if the value shows up somewhere rather than being mysteriously swallowed. On the other hand, it might make sense to return (list arg) on the theory that flatten should always return a seq. I could live with that. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
