+ * Maps each source value to the given Observable `innerObservable` regardless
+ * of the source value, and then merges those resulting Observables into one
+ * single Observable, which is the output Observable.
+ *
+ * ## Example
+ *
+ * For each click event, start an interval Observable ticking every 1 second
+ *
+ * ```ts
+ * import { fromEvent, mergeMapTo, interval } from 'rxjs';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const result = clicks.pipe(mergeMapTo(interval(1000)));
+ *
+ * result.subscribe(x => console.log(x));
+ * ```

+ * @see {@link merge}
+ * @see {@link mergeAll}
+ * @see {@link mergeMap}
+ * @see {@link mergeScan}
+ * @see {@link switchMapTo}
+ *
+ * @param innerObservable An `ObservableInput` to replace each value from the
+ * source Observable.
+ * @param concurrent Maximum number of input Observables being subscribed to
+ * concurrently.
+ * @return A function that returns an Observable that emits items from the
+ * given `innerObservable`.
+ * @deprecated Will be removed in v9. Use {@link mergeMap} instead: `mergeMap(() => result)`
