%proving right_membership_via_left
With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of right_membership_via_left: (see dependencies)
right_membership_via_left may now be readily provable (assuming required theorems are usable). Simply execute "%qed".
