If you are using Go, you have no idea what the error you're going to receive is, because the code you call could be calling other code that you have no idea about. You might use existing code that gets modified to call into another module and then you're going to get a whole set of errors that you aren't expecting and won't be able to react to.
What this means is that you have NO way to handle errors except to just error out and bubble up. Because all you can do is look at the error, the best you can do is throw your hands up and say "okay just returning this error." How is this any better than an exception?
