But you don't have to handle errors in Go. With multi-return you just don't bother with the "err" value and happily proceed with whatever is in the first return position.
IMHO, only languages with exceptions or Sum types that encode that a return is either a value or an Err (but not both) actually do what Golang says it does (make you handle errors).
