A set of tests for the InterpreterObject has been added to enhance its reliability and maintainability. The tests check the essential functionalities such as its creation, execution, saving, loading, and destruction. Furthermore, the error logging for the Parser has been improved, now providing more precise location of detected errors. The changes improve the robustness and debugability of the code.
SaveSizeCounter is introduced and used for calculating the save size of objects. The previous method of calculating save size directly in each class was replaced with a call to the SaveSizeCounter's calc method. This results in a cleaner, more maintainable code as the size calculation logic is now centralized in one class. It is more efficient and scalable as any changes to the calculation can be made in one place and will be reflected everywhere.
