quickcheck-classes-base-0.6.1.0: QuickCheck common typeclasses from `base`

quickcheck-classes-base-0.6.1.0: 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 (Show1, Eq1, Ord1, etc.), but on GHC >= 8.5, it uses `-XQuantifiedConstraints` to express these constraints more cleanly.
