[racket-dev] Interactive Stepping

The latest student query on "users at racket-lang" comes from a student who typed an expression at the prompt and hit "Step" to single-step its evaluation.  Which is a reasonable thing to do, and one I've wished for years were possible.  How difficult would it be?

A related wish-list item: I'd like to be able to select a section of code in Definitions, hit "Step", and single-step through only that part of the code.  Sure, go ahead and EVALUATE everything before that, but don't turn on the Stepper until you get to that section of code.
