{- $constraints

Be aware of the following potential gotchas:

* Type variables of kind @*@ are assumed to have 'Ix' constraints.
  If this is not desirable, use 'makeRange' or one of its cousins.

* Generated 'Ix' instances for poly-kinded data family instances are likely
  to require the use of the @TypeInType@ extension on GHC 8.0, 8.2, or 8.4.
