In this case supercalls do make sense. Blackbox example "ObxFldCtrls"
uses it explicitly.
However, the comment on the undesireability of excessive use of
implementation inheritence (supercalls) is on the mark. Programs can
break in unexpected ways when so (ab)used. I believe, OuS recommends
delegation whenever possible, since you are then using a well published
interface.
