Okay let me rephrase. The type checker doesn't make sure you've checked the value of ok e.g. you can do this: https://play.golang.org/p/x18Rh2iwd2E https://play.golang.org/p/x18Rh2iwd2E Go constantly requires boiler-plate checks for errors, null values etc. without the type checker helping ensure you've checked for an error or null value.
