示例1: forEach

export function waitForMap<A, B>(
    obj: {[k: string]: A}, fn: (k: string, a: A) => Observable<B>): Observable<{[k: string]: B}> {
  const waitFor: Observable<B>[] = [];
  const res: {[k: string]: B} = {};

  forEach(obj, (a: A, k: string) => {
    if (k === PRIMARY_OUTLET) {
      waitFor.push(map.call(fn(k, a), (_: B) => {
        res[k] = _;
        return _;
      }));
    }
  });

  forEach(obj, (a: A, k: string) => {
    if (k !== PRIMARY_OUTLET) {
      waitFor.push(map.call(fn(k, a), (_: B) => {
        res[k] = _;
        return _;
      }));
    }
  });

  if (waitFor.length > 0) {
    const concatted$ = concatAll.call(of (...waitFor));
    const last$ = l.last.call(concatted$);
    return map.call(last$, () => res);
  } else {
    return of (res);
