    Same comment as with pop, would using Deque instead of Stack make sense?

> I am using `linkedlist` as a stack in groovy 
> as doc says, `pop()` take elm from the first
>     Stack Method  Equivalent Deque Method  
>     push(e)       addFirst(e) 
>     pop()         removeFirst()
> so a `linkedlist` [1,2,3] should pop() 1 2 3
> and it does in Java, but does NOT in groovy. WHY?
> test below
> {code:title=A.java}
> import java.util.*;
>     
> public class A{
>     
>     
>     public static void main(String[] args){
>     
>         String[] x = "1/2/3/".split("/");
>         LinkedList <String> stack = new LinkedList<String>(Arrays.asList(x));
>         System.out.println(stack.pop());
>     }
