libghc-quickcheck-safe-dev 0.1.0.1-2build1 (powerpc binary) in ubuntu zesty

 QuickCheck-safe reimplements the quickCheck functionality with a pure
 interface and a very small trusted base (see Test.QuickCheck.Safe.Trusted).
 .
 * uses the existing Arbitrary instances
 * implemented features: testing, result minimization (i.e., shrinking)
 * missing features: expected failures, label frequencies, coverage
 .
 The package is targeted at users who want to leverage SafeHaskell for
 sandboxing.

   >>> putStr $ quickCheck (inventQCGen ()) (\x -> length (x :: [()]) < 10)
   *** Failed! Falsifiable (after 18 tests and 3 shrinks):
