-- | A version of Either specialised for encoding of success or failure
--   
--   The primary motivation for creation of this package was the need for
--   the <a>Alternative</a> instance of <a>Either</a>, which there is no
--   sane way to implement. The type provided by this library extends
--   <a>Either</a> in a way to provide the missing instance.
