This library provides classes that emulate the behavior of GHC's constraint
tuple syntax. Unlike GHC's built-in constraint tuples, the classes in this
library can be partially applied.

This library exposes two different modules that are semantically identical, but
compile to slightly different Core:

* `Data.Tuple.Constraint`: A `CTupleN` class compiles to a dictionary data type
   with `N` fields.
* `Data.Tuple.Constraint.ClassNewtype`: A `CTupleN` class compiles to a newtype
   around the corresponding built-in constraint tuple type with `N` arguments.
