Hi all. I'm new to this mailing list. (and still a relative newbie in Haskell - learning GraphicsLib) Because the Wish List did not work (maybe it is my browsers fault), I now write it to this list.
I found the zipWithN functions in the standard libs, but imho it would be much more comfortable to use operators like in this example: zipWith6 :: (a->b->c->d->e->f -> g) -> ([a]->[b]->[c]->[d]->[e]->[f] -> [g]) zipWith6 f as bs cs ds es fs = f :< as >< bs >< cs >< ds >< es >< fs infixl 123whatever (:<), (><) -- lower priority than (++) (:<) :: (a->b) -> [a] -> [b] (:<) = map (><) :: [(a->b)] -> [a] -> [b] (><) = zipWith id or better: (><) :: [(a->b)] -> [a] -> [b] (><) (f:fs) (x:xs) = (f x) : (fs >< xs) (><) _ _ = [] The fibs example would now look like this: take 10 fibs where fibs = 1 : 1 : ( (+) :< fibs >< tail fibs ) instead of take 10 fibs where fibs = 1 : 1 : zipWith (+) (fibs) (tail fibs) What does you suggest/what's your oppinion to this? (maybe other operators?) - Marc _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
