Hi RJF,   
      
   Thank you for your many suggestions. But you are missing   
   the point. I have no aspiration to advance the art of   
   CAS, what ever this should mean.   
      
   I am humble reimplementer, like a painter who paints   
   a false picasso. So my art is redoing things that have   
   long before people done, maybe not anymore walking on earth.   
      
   This redoing already started with Jekejeke Prolog which   
   was done 1986 while at ETHZ. I leave advancing the art to   
   others, better endowed (funds, resources, etc..) for this   
      
   endeawour, including the mainy failures this implies. After   
   all, what is the duty of universities etc.. than to advance   
   knowledge, for all. If you don't agree with this use of   
   knowledge by me, there is no use at all of continuing   
   discussions with you.   
      
   In Switzerland, ETHZ and EPFL are funded mostly by tax   
   money. So it was already my tax money. What do I get in   
   exchange for this money? How does research fertilize   
   industry? What role could a USENET group play?   
      
   I can only conclude that you, RJF, are not in good mental   
   health state. You started your email communication with me,   
   by suggesting I should go to a library and read books,   
   i.e. use this knowledge, now I am the bad guy because   
   I dont advance the art.   
      
   You have to decide, what do you want me to do?   
   - Go to a library read books and reimplement existing stuff?   
   - Advance the art of CAS, do original and relevant things?   
   - Both? What if I want to do neither, if my needs are different?   
      
   Doing both might be your typical profile, its the typical   
   scholarly requirement. On the other hand my profile looks   
   a little bit different. I wrote like a dozen times what my   
   profile is, that I am seeking breath and not depth.   
      
   The scope of my profile is not to advance the art of CAS.   
   The current project is here to realize a cobweb of CAS   
   algorithms, with satisficing performance to get a grip   
   what the pros and cons are of the actual Jekejeke interpreter,   
      
   and what further requirements there would be, to make   
   the Jekejeke interpreter more fit for this problem domain.   
   This is one goal. There are of course also other projects of   
   mine with other goals, etc..   
      
   But you should have learned by now RJF:   
   - This project falls not into the category of standard CAS resarch   
   - its a project of mine with some very specific goals of mine   
   - These goals have less to do with CAS and more to do with logic programming   
      
   Lets make an example. How do you implement matrix inversion   
   in Prolog? Well we figured out a way to do it (also around   
   December 2016), without any destructive operations. Recently   
   I saw that XCAS uses a similar approach.   
      
   The results might flow back into the Prolog community for   
   example. Or they might get lost in the mist of time. Anyway   
   I have some loose ties to Jan Wielemaker from SWI-Prolog and   
   Ulrich Neumerkel from WG17 (ISO Standard).   
      
   So what do you exactly want from me RJF? Change my relegion,   
   make a pilgrimage to berkley, and get baptized as a CAS   
   researcher, which is far away from my real aspiration? Do   
   you think I am complete bonkers?   
      
   Bye
