@galenhuntington Many thanks for the PR! It's great to be ready for GHC 9 :)
GHC 9 is out; can we get a release? :smile:
@mithrandi Sure, I'll make a release soon. Just need to set up some CI for testing builds with GHC 9.0 first.
@mithrandi Done: http://hackage.haskell.org/package/selective-0.4.2!
Due to the implementation of simplified subsumption (https://github.com/ghc-proposals/ghc-proposals/blob/wip/spj-deep-skol/proposals/0000-simplify-subsumption.md), these two functions no longer type check under GHC 9, and so this package fails to build. The solution is simple: eta-expand their definitions.
