NAME

       Prelude::Maybe - Optional values.

SYNOPSIS

       Prelude::Maybe< a >

     = nothing()

     | just(a val)

DESCRIPTION

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