Bug report

I have an endless loop via @template TKey as array-key in this repo https://github.com/voku/Arrayy/tree/7.8.7 ... I only could fix it via removing the as array-key part in the \Arrayy\Arrayy class (voku/Arrayy@c4918ee#diff-5c5a0eceb722d6a06ff9dce22c42fb98db853e5ce760b5f6b4af84da38e1fdfbL18), and I think it's not needed there anyway because the \Arrayy\Collection\Collection class is mostly used for type checks and there TKey of array-key is working.

PS: it seems the bug was intro via "Support for union type as @template type bound"? (phpstan/phpstan-src@ac7b49e#diff-25162cb9381c440f083e718a296b61f70741c7eb3eaaa1daf3f785c301e4842f)

Code snippet that reproduces the problem

Sorry, but I couldn't find the code that produces the endless loop in PHPStan. :-/

I tried strace & --debug & -vvvvv but the only thing that happens is that the memory filled and my laptop cashed. Is there a thing that I can do to find the issue?

Anyway I could work around the issue, and maybe I used the PHPDoc annotation wrongly from the beginning, so feel free to close the issue I only wanted to write this down, so that if someone has the same issue he/she maybe find this issue and knows where to search for.
