Hi Neil, I am going over the debugger section in the manual, and realizing that I duplicated a lot of your excellent work, and that the debugger situation is really in an uncomfortable half-equilibrium. And indeed, we don't debug as well on the expression level that we did in the past; I have some thoughts about that, but I don't think they should hold back 2.0.
I wanted to write to say that I was considering combing (ice-9 debugger) for salvageable code, and pulling things over to (system vm debug). I would refactor the manual section as well. The VM debugger is not yet as nice as yours was, but it does work, and is closer to the VM implementation -- and the old one is broke. I feel bad about that, but it is how it is. Anyway, let me know if this is the wrong thing to do. Cheers, Andy -- http://wingolog.org/
