I'm surprised the author didn't talk about error handling in Go.

That is, by far, my biggest pet peeve with the language.

Most languages have try/catch patterns, but Go opted for multivariate returns and a discrete error type...without pattern matching!

At least 20% of Golang code I look at is the if err != nil pattern, which is a crazy amount of repetitive boilerplate. I don't think the must pattern is a good alternative either in many cases.
