Isn't this improbable (your assumption about the main cost) ? Even for the smallest accumulating computation such as doing an addition or consing things (which requires memory allocation, etc.), I'm not certain that there wouldn't be near-to-an-order-of-magnitude between the "going through the memory" and the "accumulator computation" ? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
