### Usage
Here is a possible [program](TODO-LINK) to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
link := &piscine.List{}
piscine.ListPushFront(link, "Hello")
piscine.ListPushFront(link, "man")
piscine.ListPushFront(link, "how are you")
it := link.Head
for it != nil {
fmt.Print(it.Data, " ")
it = it.Next
}
fmt.Println()
}
```
And its output :
```console
student@ubuntu:~/piscine-go/test$ go build
student@ubuntu:~/piscine-go/test$ ./test
how are you man Hello
student@ubuntu:~/piscine-go/test$
```
