 8 
 9 func (base * Base) Foo() {
10     fmt.Println("Base Foo : ", base.Name)
11 }
12 
13 func (base * Base) Bar() {
14     fmt.Println("Base Bar : ", base.Name)
15 }
16 
17 type Foo struct {
18     Base
19     a int 
20 }
21 
22 func (foo * Foo) Bar() {
23     foo.Base.Bar()
24     fmt.Println("\tFoo Bar : ", foo.Name)
25 }
26 
27 func main() {
28     var str string = "hello world"
29 
30     base := &Base{str}
31     base.Foo()
32 
33     str = "Ni hao"
34     foo := &Foo{Base{str}, 0}
35     foo.Bar()
36     foo.Foo()
37 }

$ go run combination.go 
Base Foo :  hello world
Base Bar :  Ni hao
    Foo Bar :  Ni hao
Base Foo :  Ni hao
