 ## Code Style and Consistency
 
-Follow Project Standards: Adhere to the code style and conventions currently used in Slang. This includes formatting, naming conventions, and structural patterns.
-Consistent Formatting: Use spaces/tabs, line lengths, and other formatting elements as defined by the existing code. Consider using linters or formatters if they are part of the project.
-Comments and Documentation: Document all public methods, significant logic blocks, and any complex code in a clear, concise manner. Each comment should add value to the code and explain why something is done, not just what it does.
