+/**
+ * Converts a higher-order Observable into a first-order Observable
+ * producing values only from the most recent observable sequence
+ *
+ * <span class="informal">Flattens an Observable-of-Observables.</span>
+ *
+ * ![](switchAll.png)
+ *
+ * `switchAll` subscribes to a source that is an observable of observables, also known as a
+ * "higher-order observable" (or `Observable<Observable<T>>`). It subscribes to the most recently
+ * provided "inner observable" emitted by the source, unsubscribing from any previously subscribed
+ * to inner observable, such that only the most recent inner observable may be subscribed to at
+ * any point in time. The resulting observable returned by `switchAll` will only complete if the
+ * source observable completes, *and* any currently subscribed to inner observable also has completed,
+ * if there are any.
+ *
+ * ## Examples
+ * Spawn a new interval observable for each click event, but for every new
+ * click, cancel the previous interval and subscribe to the new one.
+ *
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { switchAll, map } from 'rxjs/operators';
+ *
+ * const clicks = fromEvent(document, 'click').pipe(tap(() => console.log('click')));
+ * const source = clicks.pipe(map((ev) => interval(1000)));
+ *
+ * source.pipe(
+ *   switchAll()
+ * ).subscribe(x => console.log(x));
+ *
+ /* Output
+ *  click
+ *  1
+ *  2
+ *  3
+ *  4
+ *  ...
+ *  click
+ *  1
+ *  2
+ *  3
+ *  ...
+ *  click
+ *  ...
