Dear GHC devs and core libraries committee Can I draw your attention to https://gitlab.haskell.org/ghc/ghc/-/issues/21623 This ticket makes specific proposals for how to move forward on the long-standing, and increasingly painful issue of *whether or not Constraint and Type are equal in GHC's type system*. We'd love to know what you think. Please respond on the ticket. The changes affect only GHC internals, so we aren't planning a GHC proposal, but the ticket is essentially a full proposal anyway. It affects only GHC internals, but there are some users who rely on GHC internals, which is why we are seeking your opinions. Thanks Simon
