Feature request

When you install phpstan it comes with bundled packages. The problem is you never know which version will be used eg while unit testing if your package needs the same package. So your tests will fail randomly 😁¹ I'm not sure how phpstan autoloader work, maybe the problem actual only for autoload.files?

Today's case (phpstan version version is outdated and not yet have Mbstring::mb_ltrim())

Error: Call to undefined method Symfony\Polyfill\Mbstring\Mbstring::mb_ltrim()

Did PHPStan help you today? Did it make you happy in any way?
