This IS an error; if you declare such a thing in the protected
part, you should rename it. How is the compiler supposed to
know in a descendent class which one to take ? Any decision will
be necessarily an arbitrary one.

Delphi has other strange quircks; Can you tell me WHICH rec it takes
when you refer to it ?

I agree that for the sake of compatibility, we should accept this, but it is
simply bad programming to do this, so this is not a priority.
