Is the renaming of import, i.e., as HTTPException needed at the last?

I suppose there's not reason for noqa anymore.

This works great for me in the Fedora Linux RPM package. However, I still do have to ask pytest to ignore DeprecationWarning, since apparently starlette.middleware.wsgi is going away:

I need to update this PR. I'll do it today (I think).

I'm going to just ignore the warning from WSGIMiddleware.

@tiangolo This is the PR that deprecates it: encode/starlette#1504

I'm not sure if you want to import a2wsgi on fastapi.middleware.wsgi, and update the docs...

Still works for me, including the newly-ignored warning. Thanks!

How about adding proper type hints for these names?

There are several examples and places in the code base that expect detail to be any JSON-able data, not only a string (as is with Starlette).

So, only for this little type hint we still need the custom HTTPException class in FastAPI.
