> I’m not a go developer. How does go document how a function can fail? There's no magic to it. Errors are values, so it's a part of the function signature that there's an error code to check. In C++ any function can throw an exception and there's no way of knowing that it wont. It's true that go doesn't document what _kinds_ of errors it can throw, but at least I know there's something to check.
