Marshal can't handle Arrays

The marshal function can't handle types of reflect.Array.
import "launchpad.net/goyaml"
import "fmt"

type A struct {
  MyByteArray [10]byte
}

func main() {
 example := A{MyByteArray: [10]byte{1, 2, 3, 4, 5, 6, 7, 8, 9, 0}}
 data, err := goyaml.Marshal(&example)

 if err != nil {
  fmt.Println(err)
 }

 fmt.Println(data)
}
