template member method

[xushiwei]

In normal way to implement a clone method:

type Sprite struct {
    // ...
}

func (p *Sprite) CloneTo(dest *Sprite) {
   // ...
}

type Foo struct {
    Sprite
    // ...
}

func (p *Foo) Clone() *Foo {
    dest := new(Foo)
    p.Sprite.CloneTo(&dest.Sprite)
    // ...
    return dest
}

Suppose we have template member method:

type Sprite struct {
    // ...
}

// any T who have embedded Sprite member will implement Clone method automatically
func [T Sprite] (p *T) Clone() *T {
    // ...
}
