• Perfect for environment validation tools, CLI apps, and configuration loaders.
• Improved test coverage and documentation to reflect the new feature.

This release was crafted with the help of Amazon Q Developer as part of the "Quack The Code Challenge", streamlining the process of extending valitype's rule system.
