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.
