Identifier's are used to distinguish and order objects.
On many architectures a pointer to the object will suffice, but the C++ standard only guarantees that this works for two pointers pointing within the same structure or array. Classes need to inherit from Identity to use this mechanism. Identity, Identifier, and the shorthand boolean operations may have to be modified for certain architectures.
