Golang-嵌套结构中的切片

I have a deeply nested struct which contains two slices, as seen below:

package main

import "fmt"

type bar struct {
    v1 []int
    v2 []int
}

type foo struct{ bar bar }
type tar struct{ foo foo }

func main() {
    f := &tar{foo: foo{bar: bar{v1: [2], v2: [3]}}}
    fmt.Printf("Hello, playground %s", f)
}

How do I initialize the two slices? Or how do I get this code working?

Here is the Golang Play for it: http://play.golang.org/p/zLutROI4YH.

    v1 and v2 are slices. The way you initialize those is with make([]int, YOUR_INITIAL_SIZE) instead of [2] and [3].
