// {{Aroush-2.9 Port issue, need to mimic java's IdentityHashMap
/*
* From Java docs:
* This class implements the Map interface with a hash table, using
* reference-equality in place of object-equality when comparing keys
* (and values). In other words, in an IdentityHashMap, two keys k1 and k2
* are considered equal if and only if (k1==k2). (In normal Map
* implementations (like HashMap) two keys k1 and k2 are considered
* equal if and only if (k1==null ? k2==null : k1.equals(k2)).)
