This issue is just to track all of the new features and their implementation state in this project.
As with all releases, we will not necessarily to support all features until closer to the full release when everything the features are stabilised.

Please be patient.

✅ using Declarations and Explicit Resource Management (#7479)

export function doSomeWork() {
    using file = new TempFile(".some_temp_file");

    // use file...

    if (someCondition()) {
        // do some more work...
        return;
    }
}

This will require new AST based on the estree AST

✅ lib.d.ts Updates (#7451)
