  	this.name = name;
  };
  
  Person.prototype.set_name4 = function(name) {
  	this.name = name;
  };
  
  Person.prototype.set_name5 = function(name) {
  	this.name = name;
  };
  
  var person = function(pname) {

  			name: name
  		};
  		
  		return {
  			get_name: get_name.bind(person),
  			set_name: set_name.bind(person)
  		};
  	}
  
    return init;
  }();
  
  var _p = new Person('John');
  var _c = person('John');
  var _b = makePerson('John');
