463-477: Test cases required forcheck_script_dependencies_and_check_gasmethodThe
check_script_dependencies_and_check_gasmethod appears to be correctly implemented insession.rsand calls the corresponding method inloader.rs. However, there are no test cases found for this method. It is important to add test cases to ensure that this method is properly tested for various scenarios, including edge cases and error handling.
- File:

id_locparameter is passed todefine_fun. Ensure that this parameter is used correctly in the function definition.Verification successful
id_locis used correctly within thedefine_funfunction.The
id_locparameter is passed to thedefine_funfunction and is used to initialize theid_locfield of aFunEntrystruct, which is consistent with its intended purpose.
