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