Hm.  transformRuleStmt already does special-case utility statements to
some extent, so my inclination would be to make it do more of that.
However, it looks like that might end up with rather spaghetti-ish
code, as that function is kind of messy already.

Or we could abandon the notion of adding the assertion.  I don't
know how much work it's worth.
