PR Self Review Checklist:

• Code is not following code style guidelines
• Bad naming: make sure you would understand your code if you read it a few months from now.
• KISS: Keep it simple, Sweetie (not stupid!).
• DRY: Don't Repeat Yourself.
• Code that is not readable: too many nested 'if's are a bad sign.
• Performance issues
• Complicated constructions that need refactoring or comments: code should almost always be self-explanatory.
• Grammar errors.
