I think it's done. All but 4 of the tests pass: - I have new versions of arrowform1 and T5283 that pass. - The type error message for T5380 has changed. - The gimmick used by arrowapply4 is incompatible with the new representation, so this test should be dropped. _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
