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

I'm certainly fine with going back to discussion. Simon PJ, much of your review was improvements/edits, and after those are incorporated, which are the highest priority, deal-breaker issues for you? In particular, the requirement to use reallyUnsafePtrEq# received some subsequent discussion. If we require at least one mutable field for a constructor to have physical equality, then reallyUnsafePtrEq# can be avoided both in derived or handwritten equality functions. Does that improve your assessment? Best, -Ryan On Thu, Mar 1, 2018 at 3:48 AM, Simon Marlow wrote:

Simon has provided a detailed review (thanks!) so I think we'll need some time to digest those comments and suggestions and modify the proposal. In light of that shall we put the proposal back into the discussion phase for now?

Cheers Simon

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/8

Is this a sign that the proposal is not yet as polished as would hope for?
