Prelude::Maybe - Optional values.
Prelude::Maybe< a > = nothing() | just(a val)
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.
