While I basically agree with your comment, this is not what DoDi meant 
if you look at his answer to my question what he means with that. His 
point is the missing possibility to alias only a subset of an interfaces 
function to a delegate which seems to be supported in Delphi and which 
is reported here: http://bugs.freepascal.org/view.php?id=16531
