I agree, there's absolutely no need to treat $ differently in H'. The
situation will already be better than it is now, since by the special
treatment of . (and - and !, which I also agree with), there will be a
precedent to follow (assuming it gets accepted of course). That alone
makes it much easier to define the meaning of extensions like $ in TH.
