And I'd like it to be changed too. I'm paid for writing SW in Haskell, and I want to have a standard. At the same time I'm (probably unusual) Haskell fan, so I want new cool features. Don't you see a conflict of interests? https://www.reddit.com/r/haskell/comments/4oyxo2/blog_contributing_to_ghc/d4iaz5t > > > And > > the same will be true for Haskell2020.

Haskell2020 will not include TemplateHaskell, GADTs, etc. Haskell Prime committee will never catch up if GHC will continue adding new extensions. In 2020 everybody will use pattern synonyms, overloaded record fields and TypeInType, so the standard will be as far from practice as it is now. The whole idea of language extensions, as it is right now, works against Haskell Prime. https://www.reddit.com/r/haskell/comments/46jq4i/what_is_the_eventual_fate_of_all_of_these_ghc/d05q9no I abandoned my CStructures proposal because of that. I don't want to increase entropy. https://phabricator.haskell.org/D252 > > > > We can continue pretending that Haskell is standard-defined > > language, > > but it will not help to change the situation. > > But writing a new standard that encompasses prevalent usage will help > to change the situation.

I see only one real way to change the situation -- standardize all widely used extensions and declare anything new as experimental unless accepted by the Haskell Prime Committee. Probably there are other ways, but we need to cleanup the mess ASAP. New extensions only contribute to the mess -- that is my point. > > Richard _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users
