}

this.module = module

// chandler_joey.js
this.chandler = Object.create(module.parent.exports.ross) // module.parent will be "ross" if the current file is required
                                                          // by the "ross" module in "friends" through module.require
this.chandler.name    = 'Chandler'

this.chandler.surname = 'Bing'

this.joey = Object.create(module.parent.exports.ross) // same as in "chandler"

this.joey.name    = 'Joey'

this.joey.surname = 'Tibbiani'

// friends.js
;(function(one) {
  for (name in one) console.log(one[name].get_fullname())
})(require('./ross').module.require('./chandler_joey')) // the actual usage

// usage:
// $ node friends.js //=> Chandler Bing
                     //   Joey Tribbiani
