        Additionally, it's very useful to us if you can provide a "straw API" — what the
        method signatures would look like, for example, even if the method and class names are still
        in flux. This can make the feature you're suggesting much clearer to us.

  - type: textarea
    attributes:
      label: (Optional) What would the method signatures for your feature look like?
      placeholder: |
        e.g.,

    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

/// warning | Alertes

Les fonctions auxiliaires `fake_password_hasher` et `fake_save_user` ne servent qu'à démontrer un flux de données possible, mais elles n'offrent évidemment aucune sécurité réelle.
