Why bother to write (+ 1 2 3 4 5 6 7 8 9 10) when you could just write 55? In order to write (+ 1 2 3 4 5 6 7 ...) you need more than just the length of the list, you need to know its contents as well. (let [s (take 10 (infinite-stream-of-random-integers))] (applyn 10 + s)) will work right---you know the length of s---but you're not going to be able to just directly apply +. I'm skeptical for a different reason: user=> (let[t(fn[](apply + '(1 2 3 4 5 6 7 8 9 10)))] (time(dotimes [_ 1000000] (t)))) "Elapsed time: 1736.91518 msecs" nil user=> (let[t(fn[](applyn 10 + '(1 2 3 4 5 6 7 8 9 10)))] (time(dotimes [_ 1000000] (t)))) "Elapsed time: 2375.503756 msecs" nil -- Ben Wolfson "Human kind has used its intelligence to vary the flavour of drinks, which may be sweet, aromatic, fermented or spirit-based. ...
