```
class C {
         int uuid;
	int toSerial(){ // int is the proxy type
		return uuid;
	}
	void fromSerial(int i){
	        // do uuid lookup and assign this if this could be ref
	}
}

...

during serialization check if type has a toSerial and call that 
instead of serialized directly, in this case uuid will be written 
instead of the class contents. the actual class contents will be 
serialized else where
