I know Guillaume proposed to do it in the context of the editor. I'm unconvinced that that's the right way to go. At any rate, integrating into an existing bit of infrastructure (def'ns or inter's) is going to be much more complex than an "off-line" prototype that people can critique. So we should do that regardless.
You and Kathy raise good and interesting points. This tells me that there is not yet a good answer to *where* the stepper should run. I believe this is quite separable from *how* the stepper runs, ie, how it displays the sequence of expressions. Since I feel that is currently the biggest problem with it, it seems wise that we focus on the latter for now. Once we make some real progress on that high-order bit, we can see what percolates up. Do others agree that this is the high-order bit? If not (and perhaps even if so), can you articulate why?
