Yes, but who is the ancestor? You always have to look for that.

I guess, Larry means something like

|inherited method (...);

instead of the specific

|ancestor.method (...)

call in Turbo (Object?) Pascal.

Yeah, right. But it would be easier to just write the equivalent to
$WHATEVER_THE_CURRENT_ANCESTOR is instead of specifying it each time.
Sometimes the object hierarchy might change a little bit.
