I haven't seen this bug report but that's definitely something to be looked into.

The stepper does know how to recover the source of a procedure with just such a trick. And yes, when Stephen Chang constructed the stepper for the lazy language, it came up too. ;; --- For your specific task, you may wish to look into Redex. We tend to think of Redex as a programming language modeling tool, but Robby uses it in his classroom presentations to show reduction sequences for specific functions. Since Redex is hosted within Racket, you could also hook up a gui or a web browser or whatever to show things. (One of the things we discovered a couple of years back is that Redex is a fantastic way to show probabilistic algorithms, but now we're beyond middle school :-) a bit) -- Matthias _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
