GHC 9.4 compatibility

Open athas opened this issue 3 years ago • 0 comments

fgl fails to compile with GHC 9.4 because ST is no longer an instance of MonadFail: https://github.com/haskell/core-libraries-committee/issues/33

I am trying to work out the best way to fix it. One solution may be to drop the requirement that a GraphM monad must also be a MonadFail.
