   unify_with_occurs_check() does not mean only the   
   Prolog doesn't like it. It means that Prolog has   
   proved that it is semantically unsound.

   My 28 year goal has been to make   
   "true on the basis of meaning" computable.   
      
   This required establishing a new foundation   
   for correct reasoning.
