     7  ```go
     8  var retrySum uint
     9  err := Do(
    10      func(uint) error { return fmt.Errorf("%d", retrySum) },
    11      WithOnRetry(func(n uint, err error) { retrySum += 1 }),
    12      WithDelay(time.Nanosecond),
    13      WithLastErrorOnly(true),
    14  )
    15  
    16  fmt.Println(err)
