     - An optional thunk that is called when the breakpoint is hit.

thunk return value could be specified to control flow:

 #<unspecified> -- do the normal thing
 #f -- go interactive
 #t -- do step (or whatever)
 (pk ARGS...) -- emulate `pk' (display ARGS and value after evaluation)
 (warn TEST MSG . SUBST) -- TEST value (after evaluation),
                            if true, emit MSG and use SUBST value
 positive number -- do step multiple times
 negative number -- do something else
 etc

also, thunk access to its "##-site" could allow self-replacement.
