 A Submethod is a method that is not inherited by child classes. They are
-typically used for per-class initialization and tear-down tasks which are
-called explicitly per class in an inheritance tree, usually for enforcing a
-particular order. For example object construction with the C<BUILD> submethod
-happens from the least-derived to most-derived, so that the most-derived
-(child) classes can depend on the parent already being initialized.
