proposition: Lemma length_ByteString_push : forall (bs' : ByteString) (b : bool), length_ByteString (ByteString_push b bs') = S (length_ByteString bs').
proof: Proof. simpl; clear; destruct bs'; simpl. unfold ByteString_push; simpl. destruct (eq_nat_dec padding0 7); intros; simpl; subst. - unfold length_ByteString; simpl; omega. - unfold length_ByteString; simpl; omega. Qed.
