How should I use QuickCheck for testing a property that is a nested implecation such as (A ==> B) ==> C ? 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
