laziness again...

Hi, I'm a bit puzzled by this observatio that I made. I have a function that, pseudocoded, lookes somewhat like f i as bs cs = ins i (f (i+1) as) ++ ins i (f (i+1) bs) ++ ins i (f (i+1) cs) where ins i = manipulates the first element of the list Now, without the ins'es, the function appears to be lazy, i.e I can "take" a part of it without evalutating the rest. With the ins'es, the whole thing seems to be calculated as soon as I touch it. Is this obvious? Or is my observation wrong? -kzm -- If I haven't seen further, it is by standing in the footprints of giants
