The sentry_asgi middleware uses the `__qualname__` or  `__name__` attributes of the `endpoint` https://github.com/encode/sentry-asgi/blob/c6a42d44d31f85885b79e4ee898683ecf8104971/sentry_asgi/middleware.py#L84

Looking at the Starlette implementation `endpoint` is a `Callable` https://github.com/encode/starlette/commit/34d0097feb6f057bd050d5057df5a2f96b97384e#diff-34fba745b50527bfb4245d02afd59246R100 which as far as I can tell is analogous to the `view` function which is matched here https://github.com/simonw/datasette/blob/90d4f497f9b3f6a5882937c91fddb496ac3e7368/datasette/utils/asgi.py#L96 .

A slight issue is that  `__qualname__` is matched *first* in the sentry_asgi middleware, and `__name__` is used if that doesn't exist. I think (please correct me if I am wrong) that for datasette, the `__name__` is what should be used. For example, when using the development fixtures and hitting `http://127.0.0.1:8001/fixtures/compound_three_primary_keys` the `view` function that is matched gives:

```python
>>> view.__qualname__
'AsgiView.as_asgi.<locals>.view'
>>> view.__name__
'TableView'
```

Would `TableView` be the desired value here? Or am I looking in entirely the wrong place? :smile:
