There's really only one key difference between seqs and lists is that lists include a count private field. So the only way that you will ever have a problem in this regard is when doing a count on the data. In the case of seqs the count will be O(n) until it hits a list when suddenly it becomes O(1) and count on lists is always O(1). So just be aware that doing a count on a seq could be slow (or may not be) and there really isn't a problem. Personally I consider lists to be "slightly faster" seqs. In reality seqs are just any object that implements ISeq. So this also includes Cons, LazySeq, PersistentList, KeySeq, ValueSeq, etc. Timothy -- You received this message because you are subscribed to the Google Groups "Clojure" group.
