An interesting question. What is the goal of Haskell'? Is it to, like Python 3000, fix warts in the language in an (somewhat) incompatible way or is it to just standardize current practice? I think we need both, I just don't know which of the two Haskell' is.
I would hope it is both. Some changes simply cannot become current practice since they would not be compatible with existing code, and the only place that such changes *could* be made is in a new language version. Like you say, fail in the Monad class is one such issue that would not be backwards compatible, and couldn't become a current practice without some help. Chicken or egg first? Cheers, /Niklas
