Perhaps something like for :: Int -> Int -> (Int -> IO ()) -> IO () for begin end f = sequence_ [ f i | i <- [begin..end] ] *Main> for 1 10 print 1 2 3 4 5 6 7 8 9 10 On 25/12/2005, at 9:35 PM, Branimir Maksimovic wrote:

I've found that Haskell is pretty good in implementing recursive algorithms. Problem cames when one want's to implement non recursive algorithm by terms of recursion as Haskell does not support loops. Perhaps if we can get loops, situation will improve, but then that wouldn't be functional style.
Could you give an example of a loop you find awkward in Haskell?
Well I want simple loop for(int i =0;i<10;++i)doSomething(i); in haskell that would be for begin end f | begin /= end = do {f begin ; for (begin+1) end f} | otherwise = return ()
I've often found that you can just define a control construct in Haskell when needed (e.g., some kind of loop).
I don't know how to do that.
