[Haskell-cafe] how to break foldl' ?

Hi, say if I want to sum a list of numbers but only until it hits a max limit. Currently, I control it through the function and basically do nothing when the max is hit. However, if the list is very long, would this mean the same function would be called for the rest of the list which can be a waste of cycle ? In an imperative language, I just break/return in the middle of the loop. thanks for any help in advance. gary __________________________________ Yahoo!
