Does anybody know of a pragma or another way to make a function *non-strict* even if it does always evaluate its argument? In other words, is there a way to selectively disable the strictness optimization?
parallelize a b | False = (undefined, undefined) | otherwise = a `par` (b `pseq` (a, b)) might do, unless strictness analysis is smart enough to know that the False guard is always, well, False. --Max
