add method Value() Value to InterfaceValue.
use Value() in print to print underlying value
from interface.
before:
package main
import "fmt"
func main() {
x := []interface{} {1, "hello", 2.5};
fmt.Println(x[0], x[1], x[2], x);
}
1 hello 2.5 [<non-nil interface> <non-nil interface> <non-nil interface>]
after:
1 hello 2.5 [1 hello 2.5]
