@mkoprek Thanks for your help with this PR. Really appreciate your help on it.

Given this project only contains attributes, I wonder if having both PHPStan and Psalm is overkill?

Options I see:

• Remove Psalm from CI, and get this merged. We can create a separate PR with Psalm enabled and merge that once the Psalm PR is sorted.
• Wait until PHP 8.4 is released.

The benefit of the first option is the phpstan rules for this can be upgraded for 8.4.

Have you any thoughts on the above, or a better suggestion?

Hey,

From mine personal perspective I think using both tools is an overkill.
We are using in all projects phpstan and it is doing it job very well.

I would choose option one, I will push code with changes for it.

Thanks for fast response :)
