Just curious which one is more efficient(not that I question the vector append is slow) as it would still involve some array copy and creation(though I assume it would be very efficient as it is using the very low level i.e. sort of memcpy) whereas the single-link-list cons would always be O(1). -- You received this message because you are subscribed to the Google Groups "Clojure" group.
