Ok, I see the point you're trying to get at. Though I'm not entirely convinced, that seqs and data structures should be that much bifurcated. After all seqs _are_ data structures + possible laziness. I agree that seq should only be called if the result is used as a sequence, but I also do think it's OK to call collection/data-structure functions on seqs. There are even optimizations for that: e.g. (count (seq [1 2 3])) is O(1): https://github.com/clojure/clojure/blob/1428d43c9a5f9d0e7e89a55707868df76c69d549/src/jvm/clojure/lang/APersistentVector.java#L444 -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
