Essentially, instead of writing e.g.

DO  i @ IF  .. leave  THEN  other stuff  LOOP

you wrote

DO  i @ IF  .. leave  ELSE  other stuff  THEN  LOOP

The new LEAVE is definitely an improve, but somewhat more difficult to 
implement.  The old one is very simple:

: leave ( r:i' r:i r:retaddr -- r:i' r:i' r:retaddr )
  r>  r> drop r@ >r  >r ;
