I don't understand this finalization thing about out parameters either, but
I agree with the above statement. Borland did exactly this with IUnknown,
IInterface, TInterfacedObject - initially it just implemented because of
COM, them COM dependency was removed so it could work on Delphi and Kylix
(independent of COM).
Probably the same should then apply to the out parameter instead of
introducing something new like the 'varout' that somebody else mentioned.
