A thought on Go error handling: you could reduce the annoyance of writing the boiler plate by creating a code formatter (along the lines of goimports) that added the standard 'if (err != nil) {...}' stuff to any unhandled 'err' return in your code. Then you'd write code with just 'a, err := Thing(); b, err := Thing2(a)' and so on, and the code formatter would fill in things for you.
