I agree that this might be misunderstood in the sense of fmt.Stringer being built-in too, but if this is commonly misunderstood it probably is not a long-lasting, problematic confusion (for most purposes it simply doesn't matter wether fmt.String is a predeclared built-in or declared in the stdlib). > A much better wording would be > > The error type is a built-in interface; its definition is similar to > fmt.Stringer: > I think I disagree here. The similarity of error and fmt.Stringer is both being a one-method interface and this method has the same signature for both (no arguments, string return) but their _actual_ "definition" is pretty different as one is built-in, the other isn't.
