     "Some carefully crafted libraries make promises to their users beyond
functionality and performance.

Examples are: Fusion libraries promise intermediate data structures to be
eliminated.  Generic programming libraries promise that the generic
implementation is identical to the hand-written one.  Some libraries may
promise allocation-free or branch-free code.

Conventionally, the modus operandi in all these cases is that the library
author manually inspects the (intermediate or final) code produced by the
compiler.  This is not only tedious, but makes it very likely that some change,
either in the library itself or the surrounding eco-system, breaks the
library's promised without anyone noticing.

This package provides a disciplined way of specifying such properties, and
have them checked by the compiler.  This way, this checking can be part of the
regular development cycle and regressions caught early.

See the documentation in \"Test.Inspection\" or the project webpage for more
examples and more information.")

      "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.")
