/**
 * The moduleExpression module works around a very specific pattern we use
 * with AdonisJS, ie to bind modules as string.
 *
 * For example: With the router of AdonisJS, we can bind a controller to a route
 * as follows.
 *
 * ```ts
 * Route.get('users', '#controllers/users_controller.index')
 * ```
 *
 * Behind the scenes, we have to run following operations in order to call a
 * method on the users_controller class.
 *
 * - Dynamic import `#controllers/users_controller` module
 * - Check if the module has a default export.
 * - Create an instance of the default export class using the container.
 * - Call the `index` method on the controller class using the container.
 *
 * Router is just one example, we do this with event listeners, redis pub/sub
 * and so on.
 *
 * So, instead of writing all this parsing logic, we encapsulate it inside the
 * "moduleExpression" module.
