clojure is nice too for the example but if you'd add functions and they have arity more than 1 haskell gets better (imo of course):
user> (def concat2 (partial apply concat)) #'user/concat2 user> ((comp (partial map (partial + 5)) concat2) (filter (comp even? sum) [[2 3] [3 3] [6 6]])) (8 8 11 11) I added unnecessary parentheses to get closer to a lisp expression Prelude> ((map (5+).concat) (filter (even.sum) [[2,3],[3,3],[6,6]])) [8,8,11,11] but dont get me wrong i really like clojure :-P and the difference doesn't matter very much for me. With symbols would be... ((∘ (𝒫 map (𝒫 + 5)) concat2) (filter (comp even? sum) [[2 3] [3 3] [6 6]])) On Nov 16, 9:34 am, Ken Wesson <kwess...@gmail.com> wrote: > On Tue, Nov 16, 2010 at 3:23 AM, atreyu <atreyu....@gmail.com> wrote: > > impenetrable for builtin curried functions and . operator as comp?? i > > dont think so, haskell can be hard to read but not for those reasons > > F. e. filter when the sum of elements are even: > > > Prelude> filter (even.sum) [[2,3],[3,3]] > > [[3,3]] > > > i think is pretty readable ;-) > > user=> (filter (comp even?
