For namespace, enum, type aliase, and variable declaration, you want to remove the export modifier from the declaration, and add export default <Id>; at the end of the file.

variable statements are gonna be tricky since they can have multiple declarations, and you can not just remove the export from them all. i would say we do not need to support variable statements with binding patterns or more than one declaration.
