Yes and no... subprograms defined immediately within Wordset, if they
operate on type Set, are "primitive operations" of Set and will be inherited
(think of that as "duplicated") for type Dictionary.

But subprograms defined elsewhere that operate operate on Set are not part
of type Set, so they can't be inherited by Dictionary.

To "alias" a type with an interchangeable name, say this:

    subtype Dictionary is Wordset.Set;

(note, no "new" in there... :-)
