AFAICS, you misunderstood the example completely, or else you're proposing
syntax restrictions that are even more bizarre and unintelligible than
I thought before. We cannot have a situation where the syntax rules for
backslash commands inside an \if are fundamentally different from what
they are elsewhere; that's just going to lead to confusion and bug
reports.
