@mertcandav hi, first of all thank you so much for this great pull request! I'm the owner of this project. There are two major problems in this PR:

• There are more than half of the CI checks are failed. All of the checks need to be passed before merging this PR. Except the tests in Arch Linux container. There is a bug in Arch Linux Docker image right now:
  • https://bugs.archlinux.org/task/69563
  • https://bugs.archlinux.org/task/69576
• Recently I have started to rewrite the AST and parser (also the interpreter and compiler modules will change drastically) in rewrite branch. I can explain the motivations for this branch in a separate thread. But this PR of yours, will cause a lot of merge conflicts and modifying many lines that will be removed in rewrite branch. So it will cause some problems.

Also I would like to ask that if you created this huge diff automatically using a linting tool or manually? If it's automatically generated diff then what tool did you use and how did you do it?

If you are unable to see the CI log then I can invite you to the GitHub organization. Also I would like to invite you to our Discord server to discuss the changes.
