I stepped in the middle of this and I didn't know methods could be final until
now so maybe I'm confused to :). This is what we're talking out right?
type
TAnimal = class
procedure Fly; virtual;
end;
TBird = class
procedure Fly; override;
end;
THawk = class
procedure Fly; final; // does it require override too or just final?
end;
The idea is that now if you do:
procedure FlyHawk(hawk: THawk);
begin
hawk.Fly;
end;
The compiler can just call THawk.Fly instead of using the VTable because it
knows that no class in another unit overrode Fly after THawk. The same applies
if the entire class is final too I would presume.
