How to add backbone.cocktail to webpack?

Question

backbone.js

I am moving a large project to webpack. We use backbone.cocktail
Written by a small loader

{ test: /backbone\.js$/, loader: "util/backbone.coctail"}

in backbone.cocktail.js

module.exports = function () {
    if (this.cacheable) this.cacheable();

    // This is an async loader
    var loaderAsyncCallback = this.async();

    var slug = 'var Backbone = require(' + JSON.stringify("backbone") + ');\n'
        + 'var Cocktail = require(' + JSON.stringify("backbone.cocktail") + ');\n'
        + 'Cocktail.patch(Backbone);\n'
        + 'module.exports = Backbone;';

    loaderAsyncCallback(null, slug);
};

For obvious reasons, after assembly, it turns out that we load ourselves

/***/ 5:
/***/ function(module, exports, __webpack_require__) {

  var Backbone = __webpack_require__(5);
  var Cocktail = __webpack_require__(148);
  Cocktail.patch(Backbone);
  module.exports = Backbone;

/***/ },

Perhaps someone has already experienced something similar?
