Why utils are bad, an example

The article details a real-world problem caused by organizing code into horizontal 'utils' modules (e.g., payment_utils, email_utils), which led to circular dependencies and a broken import chain in Python. It argues for a 'vertical modules' approach based on domain concepts (like putting all payment-related code, including emails, together) to create more maintainable and less fragile software architecture.
