I can't answer for Elias, of course, but for the use cases I have in mind I think it wouldn't work. I think Elias' idea is that you would have arrows drawn over the text, pointing from one symbol in the source code to another one. The DrRacket IDE does this to highlight bound occurrences, for example; I have attached a screenshot.
