Question

Rant: Should I call "inherited" in the constructor of a class derived from TObject or TPersistent?

constructor TMyObject.Create;
begin
 inherited Create;   // Delphi doc: Do not create instances of TPersistent. Use TPersistent as a base class when declaring objects that are not components, but that need to be saved to a stream or have their properties assigned to other objects.    
 VectorNames := TStringList.Create;
 Clear;
end;

Yes. It does nothing, true, but it’s harmless. I think there is value in being consistent about always calling the inherited constructor, without checking to see if there is, in fact, an implementation. Some will say that it’s worth calling inherited Create because Embarcadero might add an implementation for TObject.Create in the future, but I doubt this is true; it would break existing code which does not call inherited Create. Still, I think it is a good idea to call it for the reason of consistency alone.
