proposition: Lemma lacv_estc: forall g t_info from to v, from <> to -> graph_has_gen g to -> enough_space_to_copy g t_info from to -> enough_space_to_copy (lgraph_add_copied_v g v to) t_info from to.
proof: Proof. unfold enough_space_to_copy. intros. rewrite <- lacv_unmarked_gen_size; assumption. Qed.
