-The 'Either' type represents values with two possibilities: a value of
-type @'Either' a b@ is either @'Left' a@ or @'Right' b@.
-
-The 'Either' type is sometimes used to represent a value which is
-either correct or an error; by convention, the 'Left' constructor is
-used to hold an error value and the 'Right' constructor is used to
-hold a correct value (mnemonic: \"right\" also means \"correct\").
