That definition of mean is wrong because it traverses the list twice. (Curiosity: would traversing it twice in parallel work any better?) As for the folds - I always *always* mix up
It might work "better" but you're still wasting a core that could be put to better use doing something more sensible. It's pretty much always best to do all the calculations that require traversing a given list in a single traversal. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
