I get what you mean but I had no idea := with the destination variable was an operator.

I just tried this right now and I didn’t an error but it was indeed not overloaded and never got called. A bug?

operator := (left, right: TObject): TObject;
  writeln('custom :=');

  c: TObject;
  c := TObject.Create;
