But Java is plagued with the same disease that hit Modula-3, distrust
of inheritance.  Done right, a base class called
SomethingOfWhichTheLengthCanBeComputed would have been defined, with a
method "length", and all these other classes would have inherited from
it.  Never too late to learn from the mistakes of the past...
