Closes #563

PHPStan is failing but it seems like the problem is because phpstan is not locked to a patch/minor version in composer.json. Same goes doctrine/coding-standard locally by the way - it spits out a couple of errors completely unrelated to my changes.

Maybe just lock those two to a specific minior version? phpstan: "~1.9.0" and doctrine/coding-standard: "~11.0.0"

These errors should be resolved on master now. I pushed commits that fixed them yesterday. I'm not sure why they're failing again here.

I was just in the process of merging master into this branch to fix the phpstan :) Thanks!
