Overview

This is subclassing from Module so that instances of this type will be modules. The reason why we want that is because that means those instances will automatically get bound to the constant names they are assigned to by Ruby. As a result, we don’t need to do any matching of constants to type variables to bind their names, Ruby will do that automatically for us and we get the name method for free from Module.
