arrays - Does go garbage collect parts of slices?

Question

If I implement a queue like this...

package main

import(
    "fmt"
)

func PopFront(q *[]string) string {
    r := (*q)[0]
    *q = (*q)[1:len(*q)]
    return r
}

func PushBack(q *[]string, a string) {
    *q = append(*q, a)
}

func main() {
    q := make([]string, 0)

    PushBack(&q, "A")
    fmt.Println(q)
    PushBack(&q, "B")
    fmt.Println(q)
    PushBack(&q, "C")
    fmt.Println(q)

    PopFront(&q)
    fmt.Println(q)
    PopFront(&q)
    fmt.Println(q)      
}

... I end up with an array ["A", "B", "C"] that has no slices pointing to the first two elements. Since the "start" pointer of a slice can never be decremented (AFAIK), those elements can never be accessed.

Is Go's garbage collector smart enough to free them?
