 * ```typescript
 * // init — bind both operations to the budget
 * const notifications = yield* AWS.Budgets.DescribeNotificationsForBudget(budget);
 * const subscribers = yield* AWS.Budgets.DescribeSubscribersForNotification(budget);
 *
 * // runtime
 * const { Notifications = [] } = yield* notifications();
 * for (const notification of Notifications) {
 *   const result = yield* subscribers({ Notification: notification });
 *   const recipients = (result.Subscribers ?? []).map((s) => s.SubscriptionType);
 * }
