So one thing I’d like to highlight, that I don’t know if we could bake into ghc safely and might not be relevant here is: At least in some cases, implementations of EQ may use “reallyUnsafePtrEquality#”, as a never false positive check that two heap values are the same heap object. Naively this seems like it’s probably orthogonal to the matter of Eq being a single or double method type class, but I figure it’s worth asking out loud On Wed, Oct 20, 2021 at 4:29 PM Joachim Breitner <[email protected]> wrote: > Hi, > > parallel work… should have linked to > https://gitlab.haskell.org/ghc/ghc/-/merge_requests/6793 > earlier.
