Now, you might ask why this feature was added.
Simply put, to give flexibility to the developers. I believe that you should build your own structures however you might like and customize to your liking. In addition, decorators now unofficially work with modules! Feel free to use TypeScript experimental decorators to augment and customize your classes.
