Jonathan, I don't believe your wording is equiavalent. The wording that we
agreed on might seem contorted, but there was good reason for it: we wanted to
make clear that "vacuous expressions" were defined extensionally (we provide a
list of constructs considered vacuous), not intensionally (anthing that can be
statically inferred to return () or error() is by definition vacuous). Your
revised wording fails to capture this distinction.

For example, someone could argue that under your definition, xx[0] is a vacuous
expression: but it isn't.
