I am learning basic data structures and I chose golang since it provide C
like pointers. While looking at list.go I noticed this in the Element struct
type Element {
next, prev *Element //makes sense. Doubly linked list
list *List //Why! I don't understand why there is a pointer to List
Value interface{} //makes sense. Data interface
}
