I think I disagree with this. The status quo makes it all too easy to miss that you need to check the return value for an error. IMHO, this is a growing ground for bugs when someone starts to use any of these APIs with realizing that we're mixing two values (and two types) into one return value. Just 2c, to reiterate that *I* wouldn't mind a solution like this.
