### Ellipsis

1) Make sure there is a space between an ellipsis and a word following or preceding the ellipsis.

Examples:

    Source (English):

        «««
        ...as we intended.
        ...this would work:
        ...etc.
        others...
        More to come...
        »»»

    Result (German):

        «««

Conversion scheme:

    Source (English):

        <abbr title="{full phrase}: {other information}">{abbreviation}</abbr>

    Result:

    opt Tasks
        operation -->> tasks: Send background tasks
    end
    opt Raise other exception
        tasks -->> dep: Raise other exception
    end
    Note over dep: After yield
    opt Handle other exception
        dep -->> dep: Handle exception, can't change response. E.g. close DB session.
    end
```

You can combine `dataclasses` with other type annotations in many different combinations to form complex data structures.

Check the in-code annotation tips above to see more specific details.

You can also combine `dataclasses` with other Pydantic models, inherit from them, include them in your own models, etc.
