   Agreed.   
      
   Discussions like this remind me of the saying, ‘fly with the   
   eagles or scratch with the chickens’. Getting worked up about remainder   
   or modulus after decades of Forth doesn't get us anywhere, it's only   
   good for the chickens. There are other 'eagle' areas that need work,   
   such as libraries.   
      
   But Forth no longer has the critical mass for eagle topics, neither in   
   the software industry nor in the open source or hobby sector.   
      
   But to remain constructive: it is positive that at least the existing   
   standard is being maintained.
