Re: [ghc-steering-committee] Please review: Mutable constructor fields, Shepherd: Ryan Newton

I don’t mean to be negative about it. I’m sold on the motivation. It just seems quite a deep-seated change (e.g. affecting transformations in Core because mutable constructors have identity) and I don’t have that satisfying “aha” feeling when all the pieces mesh together – something that is a hallmark of Haskell. I wish I could propose a constructive alternative. It’s tiresome when people just object on somewhat vague grounds but don’t offer any concrete alternatives.

In light of that shall we put the proposal back into the discussion phase for now?

Ok, I'm not hearing any strong objections and over the long course of discussion in various venues, reactions have been mostly positive. Since committee discussion here has died down, I move to go ahead and accept this proposal if there are no further objections.

it has been quiet here, but I see new activity on https://github.com/ghc-proposals/ghc-proposals/pull/8https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fghc-proposals%2Fghc-proposals%2Fpull%2F8&data=04%7C01%7Csimonpj%40microsoft.com%7Cda6f622af1f445a397cd08d57f51491f%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636554909454432423%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwifQ%3D%3D%7C-1&sdata=AcpE8whWwCIWKuNvG%2Fmwvjay0zXbPC0mP6zxk168TAk%3D&reserved=0 Is this a sign that the proposal is not yet as polished as would hope for?
