是否可以在Go中动态引用包属性？

I'm primarily a PHP developer, and recently I started looking into Go. In PHP, I can do something like this:

<?php

class TestClass {
    public function testMethod() {
        echo "Hello!
";
    }
}

$obj = new TestClass();
$method_name = "testMethod";
$obj->{$method_name}();

?>

The output being: Hello!.

I understand that the following is not a perfect comparison, since Go does not have classes, but I'm wondering if I can do something similar with exported properties of modules in Go. For example something like this (I understand that this is not valid Go code):

package main

import "fmt"

func main() {
    name := "Println"
    fmt[name]("Hello!")
}

Is this in anyway possible? How can something similar be accomplished? Thank you.

Edit: Changed "module" to "package", since this is the proper name for what I was referring to in Go

Have no idea what is meant by 'module properties' (no such thing is known by the Go specs). Only guessing:

package main

import "fmt"

func main() {
        m := map[string]func(va ...interface{}) (int, error){"Println": fmt.Println}
        m["Println"]("Hello, playground")
}

(Also here)

Output

Hello, playground

I'm guessing you're looking for "reflection".

package main

import (
    "fmt"
    "reflect"
)

type sayer struct {
    said int
}

func (s *sayer) SayHello() {
    fmt.Println("Hello")
}

func main() {
    s := &sayer{}
    cmd := "SayHello"
    reflect.ValueOf(s).MethodByName(cmd).Call(nil)
}
