Re: [Haskell-beginners] populating a bloom filter; stymied by ST monad

getValues update initial = go initial =<< gen where go v [] = return v go v (f:fs) = do You say that this stream lazily, so I deduce that gen produce a lazy IO list. So you should be able to use gen in conjunction with easyList to get your bloom filter lazily. I'm not sure what the problem is ? How exactly do you get the elements of your bloom filter from gen input ? -- Jedaï
