Fix #18548
🤖[deprecated] Generated by Copilot at 1aa8120
This pull request adds support for using for-in loops over sum types that only contain array-like types, such as arrays, slices, or structs with array fields. It modifies the checker and the C generator to handle this case and adds a test file to verify the functionality.
