- When translating “make sure (that) … is …”, prefer the indicative after `vous assurer que` (e.g. `Vous devez vous assurer qu'il est …`) instead of the subjunctive (e.g. `qu'il soit …`).

### Quotes

- Convert neutral double quotes (`"`) to French guillemets (`«` and `»`).

- Do not convert quotes inside code blocks, inline code, paths, URLs, or anything wrapped in backticks.

def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` also has a shortcut to declare that something could be `None`, with `Optional`.

Here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

///

* If the PR can be simplified in a way, you can ask for that, but there's no need to be too picky, there might be a lot of subjective points of view (and I will have my own as well 🙈), so it's better if you can focus on the fundamental things.

### Tests { #tests }

* Help me check that the PR has **tests**.

We sometimes reject contributions due to the low quality of the submission
since low-quality submissions tend to take unreasonable effort to review
properly. Quality is rather subjective so it is hard to describe exactly how to
avoid this, but there are some basic steps you can take to reduce the chances
of rejection. Follow the guidelines listed above when preparing your changes.
