We should generally support TypeDicts. Can you go into more details of what is not working for you?

```

from anthropic.types import MessageParam

data: list[MessageParam] = [{"role": "user", "content": [{"type": "text", "text": ""}]}]

```

This for example works both in mypy and pyright. (Also autocompletion of typedict keys / literals from pylance is missing)
