bar :: Blah -> Bool bar 0 = False bar _ = True ------------------------------------------------ Fail: What? matchAltIf at 15:9 ------------------------------------------------
Fixed (I think). It didn't matter whether Blah was a data or a newtype; we got the same crash.
I'm not sure if the error is in FixSyntax.fsExp' or Case.matchAltIf itself because I don't know enough about nhc98's dictionary handling and pattern matching. Help required... :-}
It was in fsExp. It shouldn't have been flattening out dictionaries in patterns (only in expressions). Regards, Malcolm
