Class WeakRef

java.lang.Object
  java.lang.ref.Reference<T>
      java.lang.ref.WeakReference
          jfun.util.WeakRef

public class WeakRef
extends java.lang.ref.WeakReference

This class subclasses WeakReference to provide hashCode() and equals() based on reference semantics.
i.e. A WeakRef object is equal to another WeakReference object if and only if they both reference the same object.
This is because java.lang.ref.WeakReference does not satisfy the requirement of HashMap.
