I think it would be better to find a different term or constraint to
describe the situation with internally and top-levelly DEFINE'd
variables. Usually I say that the variable is bound but not assigned,
and that a reference to an unassigned variable is an error.
You are right. Of course, allowing the syntax
to mean precisely that would solve the rewrite problem.
