The test-invariant package

[Tags:benchmark, bsd3, library, test]

test-invariant is a library for providing common invariants of functions as higher order polymorphic functions. This reduces for a lot of cases the need for writing prop_ functions for QuickCheck.

>> quickCheck $ idempotent (abs :: Int -> Int)
>> quickCheck $ involutory not
>> quickCheck $ not . involutory (+ (2 :: Int))
