because I accidentaly discovered that when you create a new class in a unit and cast
the object you want to access protected stuff to this newly created class, then you have
access to all protected stuff without re-writing this stuff in your new class. Nice trick
to fool encapsulation. This works fine in Delphi 2 as well as Delphi 3, I had no chance to
try it in Delphi 4. So, I decided to delete all this useless code to avoid more overhead,
but I let it there just to show the diference. }
