Hedgehog will eat your typeclass bugs; profiling libraries

 This library provides Hedgehog 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, and otherwise minimal
 API overhead.
 .
 This library is directly inspired by `quickcheck-classes`.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
