Issue with config:cache and collect()

[leenooks]

• Laravel Version: 5.6.17
• PHP Version: 7.2.0
• Database Driver & Version: N/A

Description:

In config/app.php I have used many collections, eg:

        // Details on the financial periods for each key
        'financial_periods' => collect([
                0=>['name'=>'1Q','tag'=>'q1'],
                1=>['name'=>'2Q','tag'=>'q2'],
                2=>['name'=>'3Q','tag'=>'q3'],
                3=>['name'=>'4Q','tag'=>'q4'],
        ]),

And while this works fine for the application (HTTP or console), if I use artisan config:cache which completes successfully, the app (HTTP or Console) then fails with

Fatal error: Uncaught ReflectionException: Class config does not exist in /var/www/html/vendor/laravel/framework/src/Illuminate/Container/Container.php:767

Removing bootstrap/cache/config.php clears the problem.

Is it not possible to use collections in config/app.php?

Steps To Reproduce:

In config/app.php just add a value using a collect().

Nope.
