This looks like a neat library! I really like the inheritance aspect, seems quite useful to define standard flags and arguments.

Looks good! How do you feel it compares to something like Typer/Click?

It's entirely based on class/typed field definitions as opposed to functions.

It's also built on top of `argparse`, maintaining compatibility with their APIs and re-using their parsing logic.
