Moves the workaround added in c1ef28f from Exp.hs to ExpWithGhcCF.hs When I updated the CI image from 9.4.3 to 9.4.6 the ExpWithGhcCF test started to fail on the 9.4.6 nightly test with Other error: panic! (the 'impossible' happened) GHC version 9.4.6: refineFromInScope I've done some testing and I've found: Using ghc <= 9.4.4: The -fno-specialise workaround isn't need at all Using ghc 9.4.5 and 9.4.6: It needs the -fno-specialise workaround in ExpWithGhcCF, not in Exp. Otherwise the ExpWithGhcCF test fails, not the ExpWithClashCF like mentioned in the original commit msg.
