This points out why my attempts failed! Three classes not just one!

Thank you, ikegami, thank you!

    Database handles and statement handles have different methods, so they are two different classes (::db and ::st). DBI itself provides global static methods. There's a fourth class (::dr) for database drivers.

    DBI determines the name of the database handle class and the statement handle class based on the package used to create the connection ($pkg->connect), so there's no need to tell DBI about your ::db and ::st class. On the flip side, you need to create all three subclasses even if you only want to subclass one.

      Found the documentation, thank you, here.
