+/**
+ * Combines the source Observable with other Observables to create an Observable
+ * whose values are calculated from the latest values of each, only when the
+ * source emits.
+ *
+ * <span class="informal">Whenever the source Observable emits a value, it
+ * computes a formula using that value plus the latest values from other input
+ * Observables, then emits the output of that formula.</span>
+ *
+ * <img src="./img/withLatestFrom.png" width="100%">
+ *
+ * `withLatestFrom` combines each value from the source Observable (the
+ * instance) with the latest values from the other input Observables only when
+ * the source emits a value, optionally using a `project` function to determine
+ * the value to be emitted on the output Observable. All input Observables must
+ * emit at least one value before the output Observable will emit a value.
+ *
+ * @example <caption>On every click event, emit an array with the latest timer event plus the click event</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var timer = Rx.Observable.interval(1000);
+ * var result = clicks.withLatestFrom(timer);
+ * result.subscribe(x => console.log(x));
+ *
+ * @see {@link combineLatest}
+ *
+ * @param {ObservableInput} other An input Observable to combine with the source
+ * Observable. More than one input Observables may be given as argument.
+ * @param {Function} [project] Projection function for combining values
+ * together. Receives all values in order of the Observables passed, where the
+ * first parameter is a value from the source Observable. (e.g.
+ * `a.withLatestFrom(b, c, (a1, b1, c1) => a1 + b1 + c1)`). If this is not
+ * passed, arrays will be emitted on the output Observable.
+ * @return {Observable} An Observable of projected values from the most recent
+ * values from each input Observable, or an array of the most recent values from
+ * each input Observable.
