proposition: Lemma safe_to_copy_complete: forall g i, safe_to_copy_to_except g (S i) -> safe_to_copy_gen g i (S i) -> safe_to_copy g.
proof: Proof. intros. unfold safe_to_copy_to_except in H. unfold safe_to_copy. intros. destruct (Nat.eq_dec n i). - subst. assumption. - specialize (H (S n)). simpl in H. apply H; auto. Qed.
