We could also argue that from Guix’s point of view GHC 8.8/8.10 is (right now) unstable, because our entire set of Haskell packages is built with GHC 8.6 (and thus untested with higher versions of base). We also have python-next@3.9.2 on master with (I think) exactly the same purpose. So, unless there’s any strong objections I’ll be bold and rename GHC>8.6 to ghc-next, explaining the situation in a comment. > But seeing as there isn’t much interest in a > Haskell update, applying to ‘master’ seems like a better idea. I’m counting three people (John, you and me) interested in getting Haskell back into shape, so let’s just do it :) Cheers, Lars
