@adamgundry asked "This raises the question of how to test it in CI..", haskell-ci has support for that.

I won't merge this as this adds a non-trivial dependency. Currently GHC-9.12 is excluded CI as dupIO doesn't allow it.

It seems GHC-9.10 has to be excluded as well as GHC-9.10.2 major-bumped the ghc-prim version
