%proving empty_disjunction_eval

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
empty_disjunction_eval:
(see dependencies)

empty_disjunction_eval may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
