 With kind polymorphism, there is quite a bit going on behind the scenes that
 may be invisible to a Haskell programmer. GHC supports several flags that
 control how types are printed in error messages and at the GHCi prompt.

   for the time being; it is expected that these will be brought in line

   data constructors are as follows:

      * All kind and type variables are considered specified and available for
        visible type application.

      * Universal variables always come first, in precisely the order they
        appear in the type delcaration. Universal variables that are
        constrained by a GADT return type are not included in the data constructor.

      * Existential variables come next. Their order is determined by a user-

        in the data constructor's type and doing a stable topological sort.
