DESCRIPTION

18       A  value is either of type a , represented as just(a) , or empty. Maybe
19       is often useful for computations which can possibly fail,  for  example
20       looking  up  values  in  a dictionary. Because the nothing value can be
21       stored, this is often more useful than Exceptions on failure.
