All checks have passed 🎉 @TomasVotruba I am merging it ;)

[samsonasik]

@mfn @dorrogeray Please try latest dev-main now, it should be faster

composer config minimum-stability dev
composer config prefer-stable true
composer require --dev rector/rector:dev-main

Tested on rector-src code base, it got almost twice faster :)
