Sure. Ichbiah bet that the addition or removal of a use clause could 
cause compilation errors, but could not give a working program with a 
different meaning (a different resolution).

John Goodenough came up with such a case (a very contrived case, 
involving several levels of generics). I'm not sur that Ichbiah offered 
the bottle... The so-called beaujolais effect was fixed in Ada95.
