Summary of Changes

Hello @lixin-wei, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a minor but important build issue by ensuring that the rfl/Literal.hpp header is fully self-contained. Previously, it lacked a direct include for <climits>, which could cause compilation failures in environments where this dependency was not implicitly provided by other includes. The change explicitly adds this include, making the header more robust and independent.

Highlights

• Dependency Fix: The rfl/Literal.hpp header was not self-contained, leading to potential compilation issues when included independently.
• Missing Include Added: Added the necessary #include <climits> to rfl/Literal.hpp to resolve the self-containment problem.

Code Review

This pull request aims to fix a missing include in rfl/Literal.hpp to make it self-contained. The diagnosis is correct, but the wrong header has been included. The file uses std::numeric_limits, which requires the <limits> header, but <climits> was added instead. My review includes a suggestion to correct this.
