> I agree with them. While handling errors everywhere is a little painful to write, it enforces better practices by making you acknowledge that things could fail and ignore, handle, or pass the buck.

There are better ways of accomplishing the same thing though, one way is the Either monad in Haskell. Here's an example I post sometimes comparing error handling in Go to Haskell's either monad:

    func failureExample()(*http.Response) {
        // 1st get, do nothing if success else print exception and exit
        response, err := http.Get("http://httpbin.org/status/200")
        if err != nil {
            fmt.Printf("%s", err)
            os.Exit(1)
        } else {
            defer response.Body.Close()
        }
    
        // 2nd get, do nothing if success else print exception and exit
        response2, err := http.Get("http://httpbin.org/status/200")
        if err != nil {
            fmt.Printf("%s", err)
            os.Exit(1)
        } else {
            defer response2.Body.Close()
        }
    
    
        // 3rd get, do nothing if success else print exception and exit
        response3, err := http.Get("http://httpbin.org/status/200")
        if err != nil {
            fmt.Printf("%s", err)
            os.Exit(1)
        } else {
            defer response3.Body.Close()
        }
    
    
        // 4th get, return response if success else print exception and exit
        response4, err := http.Get("http://httpbin.org/status/404")
        if err != nil {
            fmt.Printf("%s", err)
            os.Exit(1)
        } else {
            defer response4.Body.Close()
        }
    
        return response4
    }
    
    func main() {
        fmt.Println("A failure.")
        failure := failureExample();
        fmt.Println(failure);
    }

The equivalent Haskell code:

    failureExample :: IO (Either SomeException (Response LBS.ByteString))
    failureExample = try $ do
      get "http://www.httpbin.org/status/200"
      get "http://www.httpbin.org/status/200"
      get "http://www.httpbin.org/status/200"
      get "http://www.httpbin.org/status/404"
    
    main = failureExample >>= \case
      Right r -> putStrLn $ "The successful pages status was (spoiler: it's 200!): " ++ show (r ^. responseStatus)
      Left e -> putStrLn ("error: " ++ show e)
