I am curious about your use case for enums with configuration.

I have a compiler that creates PHP code based on some classes and enums I declare in my application. I use the resources to quickly check if there are changes and if I should recompile.

To be specific: it's creating Webonyx GraphQL type files, which are annoying to create by hand (arrays etc). Therefore we have our own abstraction with attributes.

@GromNaN that is a valid use case for these classes, right?

Works for me as a bugfix on 6.4

The cases were visible, because the enum cases are available as class constants.

Doesn't this mean that the more generic fix is to fix support for attributes on class constants?

Thanks. I'll rebase this PR later.

Sure, but that's a PHP 8.5 feature: https://wiki.php.net/rfc/attributes-on-constants

Maybe we should also add support for that already?

That RFC is for constants. Here we need class-constants, which do support attributes in PHP 8.1:

@nicolas-grekas Implemented it for class constants. I think this solution is much better :) Thanks!

Thank you @ruudk.
