golang程序运行时是否可以重新加载动态库?

Edit: (from comments) I'm looking for a way to modify parts of my program while it's running. I wrote this code only as an example. Assuming we have such a code:

for {
    t := time.Now()
    fmt.Print(t.Minute(), ":", t.Second(), " ")
    testdll.Testf()
    time.Sleep(time.Second * 2)
}

and

package testdll
import (
    "fmt"
)
//Testf 
func Testf() {
    fmt.Println("hello I'm version 1")
}

Is it possible to get this result during runtime when testdll is updated to version 2 and rebuilt?

14:29 hello I'm version 1
14:31 hello I'm version 1
14:33 hello I'm version 1
14:35 hello I'm version 2
14:37 hello I'm version 2
14:39 hello I'm version 2
