[Haskell-cafe] how to break foldl' ?

[gary ng]

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
