假設有兩個介面定義，裡面有相同名稱的方法。然後有一個類，要同時實現這兩個介面。語法上該怎麼寫才正確？

請看程式碼：

type
  IMyIntfA = interface
    ['{03A9D09A-F6C7-42BA-9C01-D3F9A43F3AFB}']
    function Hello(const S: string): string;
  end;

  IMyIntfB = interface
    ['{C2EDFFEA-95B1-43B8-9C9D-28E32A48FAE7}']
    function Hello(const S: string): string;
  end;

  TForm2 = class(TForm, IMyIntfA, IMyIntfB)
  private
    { Private declarations }

  public
    function HelloA(const S: string): string;
    function HelloB(const S: string): string;

    function IMyIntfA.Hello = HelloA;
    function IMyIntfB.Hello = HelloB;
  end;
