# Not implemented yet:

Module parsing (#2411)
I'm creating this draft PR, since I wanted to have some early feedback, and because I though I would have time to finish it last week, but I got caught up with other stuff. Feel free to contribute :)
The main thing here is that I have divided `eval()`, `parse()` and similar functions so that they can decide if they are parsing scripts or modules. Let me know your thoughts.
Then, I was checking the import & export parsing, and I noticed we are using `TokenKind::Identifier` for `IdentifierName`, so I changed that name. An `Identifier` is an `IdentifierName` that isn't a `ReservedWord`. This means we should probably also adapt all `IdentifierReference`, `BindingIdentifier` and so on parsing. I already created an `Identifier` parser.
Something interesting there is that `await` is not a valid `Identifier` if the goal symbol is `Module`, as you can see in the [spec](https://tc39.es/ecma262/#prod-LabelIdentifier), but currently we don't have that information in the `InputElement` enumeration, we only have `Div`, `RegExp` and `TemplateTail`. How could we approach this?
