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