Great idea! I like this solution a lot.

What should the API be?

```auto
from dash import Abort
from dash.exceptions import Abort
from dash import Halt
from dash.exceptions import Halt
from dash import PreventUpdate
from dash.exceptions import PreventUpdate

```

? Any other ideas?

I think I prefer `from dash.exceptions import PreventUpdate`.

I’d happily accept a PR that does this 👍
