There is also a rather good article on this subject in one of the 1989 issues of ACM's SIGPLAN. If I remember correctly the conclusion was that you can do full object-oriented programming in Ada (83), in a roundabout way. I'm sorry, but I don't remember which exact issue it was (or who the author was). Since this has been asked twice in the last month, perhaps it is a good candidate for the FAQ? T.E.D.
