This does no type-checking, under the assumption that it is being used by a containing doubly-linked list object which enforces that invariant along with others such as that <code>element.getNext().getPrev() == element</code>. See [[Doubly-Linked List#E]] for an actual implementation (which uses slightly more elaborate nodes than this).
def element {
to setValue(v) { value := v }
to getValue() { return value }
to setNext(n) { next := n }
to getNext() { return next }
to setPrev(p) { prev := p }
to getPrev() { return prev }

return element
