   The lack of dedicated PUSH/POP instructions IME has relatively little   
   direct impact on the usability of an ISA. Either way, one is likely to   
   need stack-frame adjustment, in which case PUSH/POP don't tend to offer   
   much over normal Load/Store instructions.   
      
      
   That said, a lot of John's other ideas come off to me like straight up   
   absurdity. So, I wouldn't hold up much hope personally for it to turn   
   into much usable.
