Summary of Changes

Hello @trojanc, 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 significantly enhances the feel package by introducing robust support for pointer values within the get value function. The primary goal is to ensure that when data is accessed from a context, any underlying pointer values are automatically dereferenced to provide the actual data, rather than the memory address. This change improves the usability and predictability of context data access, with careful consideration given to not alter the behavior of existing feel object pointers.

Highlights

• Pointer Dereferencing in get value: The get value function now automatically dereferences pointer values, ensuring that the actual value pointed to is returned instead of the pointer itself. This improves consistency when accessing data within contexts.
• New dereferencePtr Utility: A new internal utility function, dereferencePtr, has been added to handle the logic of recursively dereferencing pointers. It includes specific logic to avoid dereferencing internal feel object pointers (e.g., *Number, *FEELDate) to preserve their intended behavior.
• Comprehensive Pointer Handling Tests: Extensive new test cases have been added in eval_test.go to validate the correct handling of pointer values within structs, including nested structs and pointers to structs, ensuring robust behavior for the get value function.

Code Review

This pull request adds support for dereferencing pointer values in the get value function, which is a valuable enhancement. The implementation uses reflection to handle pointers, with special care taken to not dereference internal FEEL types. The logic appears sound and is well-supported by a new suite of tests covering various scenarios with pointers and nested structs. I have one minor suggestion regarding a duplicated test case.
