Why do you want to incrementally update this list a lot of times?
The question would affect the answer you get; i.e. some context
(non-monadically speaking). :D

Problem is following short program: list = [1,2,3,4,5]
advance l = map (\x -> x+1) l
run 0 s = s run n s = run (n-1) $ advance s
main = do let s = run 50000000 list putStrLn $ show s
I want to incrementally update list lot of times, but don't know how to do this. Since Haskell does not have loops I have to use recursion, but problem is that recursive calls keep previous/state parameter leading to excessive stack.and memory usage. I don't know how to tell Haskell not to keep previous state rather to release so memory consumption becomes managable.
Is there some solution to this problem as I think it is rather common?
