is that you aren't checking that what comes between the two dollar signs
looks like empty-or-an-identifier. The check for
next-char-isn't-a-digit is part of that but not the only part.
Well, I think the right way to do a full check would be with a regex, which I had hoped to avoid. However, I will now try to get one working and to address your other concerns.
Thanks for the comments.
