### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
"piscine"
)
func main() {
link := &piscine.List{}
piscine.ListPushBack(link, "Hello")
piscine.ListPushBack(link, "man")
piscine.ListPushBack(link, "how are you")
for link.Head != nil {
fmt.Println(link.Head.Data)
link.Head = link.Head.Next
}
}
```
And its output :
```console
$ go run .
Hello
man
how are you
$
```
