-// WaitGroupErr is similar to WaitGroup but allows goroutines to report error.
-// Only the first error is retained and reported back.
-//
-// Example usage:
-// 	wg := WaitGroupErr{}
-// 	wg.Add(1)
-// 	go func() {
-//			defer wg.Done()
-//			if err := ...; err != nil {
-//				wg.ReportError(err)
-//				return
-// 			}
-// 	}()
-//	return wg.Error()
-//

-	// firstErr holds the first error reported. nil is no error occurred.
