Thanks, Gary and Justin, for spotting my code mistakes. Serves me right for not double-checking the outputs at my REPL. :-P
Anyway, my examples with vectors, maps, and sets were all correct using into. I goofed on lists, because the new elements are naturally always applied to the front of the list since that is the only way to do it efficiently. This really just reinforces what others have already said above that Clojure's standard library doesn't make it easy for you to do something inefficient (like adding elements to the end of a list. Anyway, having said that, I guess I'd just make the following adjusted recommendation then: 1. When appending/prepending to vectors, maps, or sets, use into as demonstrated above. 2. When appending/prepending to lists, use concat with the same syntax as was shown with into above. Note, of course, that concat returns a lazy sequence not a true linked list, but for the purposes of beginner instruction, this should probably be fine since it will print to the REPL like a list and provides the same API as a list going forward. Once again, good luck with your Clojure teaching, and happy hacking! ~Gary -- You received this message because you are subscribed to the Google Groups "Clojure" group.
