IMHO, four-port debugging may be fine as an underlying model,
but is bad as a view of that model. recently, i was doing some
partial evaluation work and the strutures i was generating filled
several lines on my 4-port debugger. what i would have prefered
is a debugger ala Smalltalk where the call history is on a
click and point list in a window and clicking on item in that
list pops up another window with all the arguments listed in another
list. clicking on any one argument would print it to a third window.

sound tricky, right? actually, its wonderfully easy to use. the
debugger was one of the main reasons I switched from KEE on a LISP
machine to Smalltalk/V under DOS. I had all the debugging productivity
and none of the LISP machine overheads.
