These are great ideas! Could you please create a ghc tracker ticket with a tiny examples or two?
There may be specific technical reasons we might not be able to do so for type synonyms in ghc, but I don’t see any obvious barriers in the case of David’s excellent idea, I’ve def seen lots of great code out there where you’d really want either associated pattern synonyms or to bundle pattern synonyms with the exported public interface for a type class. I’m sure there’s some devil in the details but these sound lovely. Step -1 is making up 1-2 toy examples and explaining what and why you want it on a ghc ticket!
