Re: [Haskell-cafe] Filtering a big list into the IO monad

I want to filter a list with a predicate that returns a IO value, something that filterM is supposed to do. The problem is, filterM overflows the stack for really big lists

Are you sure it's filterM's fault? Can you post the code in question? Stack overflows are usually caused by too much lazyness, but for filterM that doesn't seem to make sense.
