proposition: Lemma index_not_points_to_binop_nil {HSLP : StringLikeProperties Char} (offset index : nat) (str : String) (H : length str <= offset + index) : index_not_points_to_binop offset index str.
proof: Proof. unfold index_not_points_to_binop. apply for_first_char_nil. rewrite drop_length; omega. Qed.
