> Subject: [docs] FOO and BAR
>
> Do you think it would be possible to write your documentation avoiding the silly usage of FOO and BAR everywhere? This is a very very old and boring joke, and does nothing to clarify what you are trying to clarify. If you could include real-world examples in your documentation, rather than "clever" programmer "jokes", learners such as myself would have far more respect for the good work you are obviously doing here.

> For example, the section on argparser is full of this sort of rubbish:
> argparse.ArgumentParser(description='A foo that bars')
>
> Under what circumstances would you ever put that in a program? Are you mad?
>
> Please take this into consideration.
