There are two separate pieces to the stepper; the annotater, which 
elaborates a user's program into one which tracks its own evaluation, 
and the reconstructor, which uses that runtime information to 
reconstruct the source code.  The first of these is relatively 
straightforward and has already been extended to cover most of the 
language.  The reconstructor is much more difficult, due to the twin 
problems of representing the store and of back-translating macros.

The upshot of this is that while 102 may contain some kind of 
debugging facility for 'Full Scheme', it will certainly not include a 
full stepper.
