Dear GHC Steering Committee We have several threads about GHC's stability in progress: - Proposal 601: GHC extension life cycle https://github.com/david-christiansen/ghc-proposals/blob/extension-lifecycle.... This introduces the notion of a "Stable" and "Experimental" extension. It was written by David C but has stalled now that he has stepped down as ED. - GHC Stability Goals https://docs.google.com/document/d/1wtbAK6cUhiAmM6eHV5TLh8azEdNtsmGwm47Zulga..., builds on #601 with general rules GR1-3. This is not a change to GHC (hence not a GHC proposal) more a clarification about how the GHC Steering Committee works. - Proposal 620: Extensions and warnings https://github.com/ghc-proposals/ghc-proposals/blob/wip/spj-extensions-and-w.... This proposal keeps moving in the same direction, unifying warnings and extensions. - Proposal 617: add -experimental flag https://github.com/ghc-proposals/ghc-proposals/pull/617. This builds on #601 by providing an enforcement mechanism. It is strongly affected by #620. It would be good to get some of this decided. Too much is in the air at the moment! Personally I think: - We can agree at least the Stable/Experimental part of #601 - The Stability Goals seem fairly uncontroversial. Shall we just make it part of the GHC Proposal process documentation - #620 is new; your views would be welcome - The approach to #617 may depend on the outcome of #620. Simon
