The way I would do it would be to make the A* a deferred word, whose 
initial value would set things up.  At the end, it would set A* to point 
at the 'final' version.

Determining that the compiled code hasn't changed could be done by 
having the accessor word !s (or whatever) set a flag (or, again, set A* 
to point to the set-things-up version).
