reflection - How to get the name of a function in Go?

Question

Given a function, is it possible to get its name? Say:

func foo() {
}

func GetFunctionName(i interface{}) string {
    // ...
}

func main() {
    // Will print "name: foo"
    fmt.Println("name:", GetFunctionName(foo))
}

I was told that runtime.FuncForPC would help, but I failed to understand how to use it.
