What are you doing with lines 1 and 2? Most people just `return fmt.Errorf("stuff the caller can't know: %w", err)` and call it a day. To me, this beats exceptions because a human can provide context; what iteration of the loop were we on, what specific sub-operation failed, etc. Spending a lot of time typing in error handling code seems OK to me. You are never going to get paged when your software is working. So you'll probably spend more of your time dealing with rare error conditions. Thus, the code spends a lot of lines capturing the circumstances around the error conditions, so you can go change a line of code and redeploy instead of spending 6 months debugging.
