 For example, see @ala Cont traverse@, with the proper 'Newtype' instance for Cont.

+Version:             0.4.0.1
 Synopsis:            A typeclass and set of functions for working with newtypes, with generics support.
 Description:         Per Conor McBride, the Newtype typeclass represents the packing and unpacking of a newtype,
                      and allows you to operatate under that newtype with functions such as ala.

                      Generics support was added in version 0.4, making this package a full replacement
                      for the original newtype package, and a better alternative to newtype-th.
