Proposal process refinements, removal of Markdown option
by Adam Gundry 15 Aug '25

15 Aug '25

Hi everyone, There is some discussion going on around refining the proposal process documentation in this PR from VitWW: https://github.com/ghc-proposals/ghc-proposals/pull/712 https://github.com/VitWW/ghc-proposals/blob/update-readme/README.rst I'm not planning to send this PR through the full review process itself, but I wanted to flag it up in case anyone from the committee wishes to comment. One point in particular to note is the removal of Markdown format as an option for authors, so that all proposals will be ReStructuredText. It seems this was agreed in principle several years ago, but not subsequently implemented, per this discussion: https://github.com/ghc-proposals/ghc-proposals/issues/560 If anyone objects to this change, please do speak up. Cheers, Adam -- Adam Gundry, Haskell Consultant Well-Typed LLP, https://www.well-typed.com/ Registered in England & Wales, OC335890 27 Old Gloucester Street, London WC1N 3AX, England

#705: Explicit Level Imports: refine specification for exports, recommendation: accept
by Arnaud Spiwack 13 Aug '25

13 Aug '25

Dear all, Matthew and team propose a very short revision of their accepted proposal for explicit level imports (this proposal, if you don't remember, is about being more precise, when importing modules, whether they need to be available to emit code, or also for Template Haskell, for better recompilation avoidance and cross-compilation support). I say revision, but really, this simply specifies some corner cases which, admittedly, were ambiguous with the original wording of the proposal. There's nothing controversial about it. We should accept very quickly. I'll be on holiday the next couple of weeks, so I won't be able to act on this for a while. I don't think it's worth waiting two weeks though. So Adam, unless someone complains, probably accept it at the end of next week. Best, Arnaud -- Arnaud Spiwack Director, Research at https://moduscreate.com and https://tweag.io.

Please guide us to a conclusion as outlined in https://github.com/ghc-proposals/ghc-proposals#committee-process Cheers, Adam -- Adam Gundry, Haskell Consultant Well-Typed LLP, https://www.well-typed.com/ Registered in England & Wales, OC335890 27 Old Gloucester Street, London WC1N 3AX, England
