Summary of Changes

Hello @aisk, 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 updates the limitations.md file to document a specific behavior in mruby where the #hash method is not called for keys in small hash tables to improve performance. This clarifies a potential point of confusion for developers relying on custom #hash implementations.

Highlights

  • Documentation Update: Added a section to limitations.md explaining that the #hash method might not be called on keys for small hashes due to performance optimizations.

## No `#hash` call for small hashes

For performance reasons, mruby avoids calling the `#hash` method on keys when a hash table is small. This means that custom `#hash` methods on key objects may not be executed.
