You could use the classical equivalence (A ==> B) <=> (~A \/ B). I'm not sure you would get very much out of the implication strategy for the nested one, anyway. > > The problem is (==>) in QuickCheck is that its type is Testable prop => > Bool -> prop -> Property rather than Testable prop => prop -> prop -> > Property. So, A ==> (B ==> C) would work but (A ==> B) ==> C won't work > when A, B, C are boolean expressions. Is there some trick to handle the > latter? > > Thanks, > > -- > Ahn, Ki Yung > > _______________________________________________ > Haskell-Cafe mailing list > [email protected] > http://www.haskell.org/mailman/listinfo/haskell-cafe > _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
