> Other features common in modern languages, like tagged unions or syntactic sugar for error-handling, have not been added to Go.

> It seems the Go development team has a high bar for adding features to the language. The end result is a language that forces you to write a lot of boilerplate code to implement logic that could be more succinctly expressed in another language.

Being able to implement logic more succinctly is not always a good thing. Take error handling syntactic sugar for example. Consider these two snippets:

    let mut file = File::create("foo.txt")?;

and:

    f, err := os.Create("filename.txt")
    if err != nil {
        return fmt.Errorf("failed to create file: %w", err)
    }

The first code is more succinct, but worse: there is no context added to the error (good luck debugging!).

Sometimes, being forced to write code in a verbose manner makes your code better.
