Це підтримується завдяки **Pydantic**, адже він має [внутрішню підтримку `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

Тож навіть із наведеним вище кодом, який явно не використовує Pydantic, FastAPI використовує Pydantic, щоб перетворити стандартні dataclasses у власний варіант dataclasses Pydantic.

If an accepted proposal is mentioned in a CL but not in the release notes, it will be
flagged as a TODO by the automated tooling. That is true even for proposals that add API.
