If this were possible, then I could use >R R> R@ with impunity _right
now_, without going to the trouble of reimplementing , as I'd know that
I could write a straightforward compatibility layer for a future system.
I would have the attitude towards return-address manipulation that I
have toward PLACE APPEND ++ SKIP SCAN and others.

But this isn't the case.  I can't roll my own return addresses just by
rolling my own stack.

Look at these words:

  : call ( r-addr -- ) >ra ;
  : cont ( -- r-addr ) ra@ magic-number + ;

  : x ( -- r-addr ) cont ahead ." It's like an XT." then ;
  x call
