go - Given a method value, get receiver object

Question

Is there a way in Go, to get the receiver object from a method value?

For example, is there any such MagicFunc that would make the following program output the string my info from the underlying Foo instance.

package main

import "fmt"

type Foo struct {
    A string
}

func (foo *Foo) Bar() string {
    return "bar"
}

func MyFunc(val interface{}) {
    i := MagicFunc(val)
    f := i.(Foo)
    fmt.Println(f.A)
}

func main() {
    f := Foo{A: "my info"}
    MyFunc(f.Bar)
}
