/**
 * Creates a new instance of a [[parallel]] node, which is used to perform a set of operations as a single combined
 * operation. The set of results is assembled into an [[array]], maintaining the order
 * of nodes provided to the [[parallel]].
 *
 * Each input node is resolved to its result and then unsubscribed immediately. This means that,
 * unlike the the [[combineLatest]], the [[parallel]] resolves to a
 * single combined result and will not update if the value of one of the input nodes is updated.
 *
 * @example **Performing multiple updates at the same time**
 * ```js
 * import muster, { parallel, set, variable } from '@dws/muster';
 *
 * const app = muster({
 *   firstName: variable('Bob'),
 *   lastName: variable('Jones'),
 *   age: variable(39),
 * });
 *
 * await app.resolve(parallel([
 *   set('firstName', 'Jane'),
 *   set('lastName', 'Doe'),
 *   set('age', 24),
 * ]));
 * // === ['Jane', 'Doe', 24]
 * ```
 * This example shows how to use the [[parallel]] to set three [[variable]]s at the same
 * time.
