There's nothing to be embarrassed about. Haskell is lazy by default. That is certainly much different than what most people are used to. So it needs to be explained to beginners. It's the same for IO laziness as for pure laziness.
:-) It's not the difficulty of understanding laziness that I find embarrassing. My Ph.D Computer Science friends that I have introduced Haskell to understand that very well. It's their "You've got to be kidding" looks when I tell them they have to call 'length' for effect or some such to get their simple programs to work. They understand Lazy IO and think that it is broken. :-) ____________________ David Place Owner, Panpipes Ho! LLC http://panpipesho.com d@vidplace.com
