synopsis:            A typeclass and set of functions for working with newtypes.
description:         Per Conor McBride, the 'Newtype' typeclass represents the packing and unpacking of a @newtype@, and allows you to operate under that @newtype@ with functions such as 'ala'. See "Control.Newtype" for documentation and examples.
