Oh, then that's something which you definitely should make yourself accustomed more -- this consept is one of the corner stones of Go. Basically, interfaces in Go are sort-of "backwards" to what they mean in other, "more mainstream" languages. The fact fmt.Fscanf() accepts an io.Reader means it accepts a value of absolulely any type which implements func Read ([]byte) (int, error). So it would accept, say, a network socket just as fine as a bufio.Reader or bytes.Buffer or any other custom type implementing that method.
