QuickCheck common typeclasses from `base`

 This libary is a minimal variant of `quickcheck-classes` that
 only provides laws for typeclasses from `base`. The main purpose
 of splitting this out is so that `primitive` can depend on
 `quickcheck-classes-base` in its test suite, avoiding the circular
 dependency that arises if `quickcheck-classes` is used instead.
 .
 This library provides QuickCheck properties to ensure
 that typeclass instances adhere to the set of laws that
 they are supposed to. There are other libraries that do
 similar things, such as `genvalidity-hspec` and `checkers`.
 This library differs from other solutions by not introducing
 any new typeclasses that the user needs to learn.
 .
 /Note:/ on GHC < 8.5, this library uses the higher-kinded typeclasses
 ('Data.Functor.Classes.Show1', 'Data.Functor.Classes.Eq1',
 'Data.Functor.Classes.Ord1', etc.),
 but on GHC >= 8.5, it uses `-XQuantifiedConstraints` to express these
 constraints more cleanly.

 This package provides a library for the Haskell programming language.
