Overview

Upon inspecting the parser, I noticed that the list functionality needed improvement. Additionally, I explored whether nested lists were supported; unfortunately, they were absent.

This pull request aims to address both deficiencies and elevate the parsing experience.

Changes Implemented

• Enhanced the functionality of the list to ensure accurate parsing and elegant rendering.
• Introduced support for nested lists, enabling deeper levels of list organization.
• Rigorously tested the functionality across various scenarios to guarantee reliability.

What's Next

• I'd like your feedback and suggestions to refine the implementation further.
• Committed to promptly addressing any critique or recommendations from reviewers.
• Eager to collaborate on advancing the parser's capabilities.

Your insights are invaluable, and I appreciate your time to review this pull request. Thank you!
