    I wonder if most associate removing items from the top of a Stack, so in 
this case would it make sense to say 
    >..similar to pop on a Deque.


> same linkedlist code different behavior between groovy and java

> 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){
