+1 for mentioning BETA. Any actual user of that language?

  I got to learn about it when I attended ECOOP'99. Never saw it outside the conference.

    BETA was the beginner's language at the University of Dortmund (Germany) back in 1996/7/8. Never saw it outside of these buildings.

        Yes, I still have my book "Object Oriented Programming in the BETA Programming Language" by Madsen/Møller-Pedersen/Nygaard with a price tag of 80 DM in 1997 (> 40 EUR now) (I now live in Berlin)

  BETA did come up in this HN post from last year: The impoliteness of overriding methods - https://news.ycombinator.com/item?id=4943538 https://news.ycombinator.com/item?id=4943538

  No, but the Racket OO system is based on BETA's implementation of OO, and Racket has some actual users. There's definitely some interesting ideas there. For example, `inner` being the opposite of super (e.g. call the subclasses implementation of this method). Some others, but I'm not sure I remember them (Augmentation?).
