JavaScript does not support operator overloading and Rhino does not have 
  any infrastructure to make it work. In particular, semantics of +, - 
etc. is hardcoded. I think you may try to look at Jython (Java 
implementation for Python) or wait when in some (distant) future 
JavaScript 2.0 and its Java implementation will materialize.
