   \ eliminate stack-cast (no longer used)
   
   \ Design Uglyness:
   
   \ - global state (values, variables) in connection with combined instructions.
   
   \ - index computation is different for instruction-stream and the
   \ stacks; there are two mechanisms for dealing with that
   \ (stack-in-index-xt and a test for stack==instruction-stream); there
   \ should be only one.
