proposition: Lemma length_ByteString_enqueue : forall b bs, length_ByteString (ByteString_enqueue b bs) = S (length_ByteString bs).
proof: Proof. destruct bs; unfold ByteString_enqueue; simpl. destruct (eq_nat_dec padding0 7); simpl. - unfold length_ByteString; simpl. rewrite app_length; simpl. omega. - unfold length_ByteString; simpl. omega. Qed.
