[ghc-steering-committee] Named defaults -- attention needed

Dear GHC Steering Committee Please see https://github.com/ghc-proposals/ghc-proposals/pull/672. This is a small amendment to a recently-accepted proposal, prompted by the discovery that the language feature accidentally breaks code that doesn't use it. It's small but important. Maybe not yet formally submitted for our attention, but we want to get something agreed and implemented before the next release. So I think it's worth your early attention. Simon
