another twist in javascript partial application. Bind

example.js

var salutator = {
  name: 'jose',
  greet: function(greeting, person) {
    console.log(greeting + ' ' + person + '. ' + this.name + ' salutates you.');
  }
};

salutator.greet('hello', 'Mark'); 
//hello mark, jose salutates you.

var goodByer = salutator._partial('greet', 'good bye');
goodByer('Remigio'); 
//good bye Remigio, jose salutates you.

proto.js

/*
 * Adds a non enumerable _partial function to the object prototype 
 * that when called returns the partial application of the given 
 * function (first parameter) with n resolved parameters.
 */

Object.defineProperty(Object.prototype, '_partial', {
  set: function(){},
  get: function(){
    var methodOwner = this;
    return function (){
      var methodName = arguments[0], 
          args = [];
      
      for (var i = 1; i < arguments.length; i++){
        args.push(arguments[i]);
      }

      return function(){
        var allArgs = args.slice(0);
        for (var i = 0; i < arguments.length; i++){
          allArgs.push(arguments[i]);
        }
        return methodOwner[methodName].apply(methodOwner, allArgs);
