so, i think, it is needed to "reassure" imperative programmers at first pages by demonstrating techiques of imperative programming, including conditional execution and IORef/MArray and only after that present more convenient alternatives. at least for my imperative feel, conditional execution, cycles, modifiable variables and arrays together form enough basis to implement any algorithm
It's weird how many different perspectives there are on what's basic Haskell. Someone asks about mapM, and everyone agrees about that - it's definitely on the short list of things we want to know - but then we go on to liftM, which I've always thought was kind of a gratuitous extra way to spell >>=. We get to IO, and of course everyone agrees that it's on the short list (even if we differ on when to get to it), but -- IORef? Can't tell if you're serious. Donn Cave, donn@drizzle.com
