I have made the following improvements.
1. Simplified the initialization block in the `__init__` method.
2. Combined `_process_args_for_options` and `_process_args_for_args` into a single `_process_args` function for centralizing the argument processing logic.
3. Used implicit unpacking for the tuple in `_OptionParser` class.
4. Replaced nested `if` statements with one-liners where possible.
5. Refactored `__getattr__` method to use a lookup dictionary for better readability and maintainability.
