var myVar = giveMeAfter('my string', 4000);

return myVar + ' with something appended';
`, {
    expose: {
        giveMeAfter(value, milliseconds) {
            var pause = pausable.createPause();

            setTimeout(() => {
                // Timeout has elapsed, so we can resume the paused code
                pause.resume(value);
            }, milliseconds);

            // Do the pause
            pause.now();
        }
    }
});
