If you wait until the final form of the code, it would seem very difficult to trace back from function symbol to its generating/binding macro. That is, how do you know which macro bound a specific function? Hope for no ambiguities, I suppose. Maybe it's not a problem, but I'd think the main point of such a grep tool is to point back to the originating code, right? Merely detecting that a specific function symbol is bound is not quite the same.
