prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  ASGIDispatch and WSGIDispatch should be importable from the top-level httpx package
  From #396:
  
  > ``ASGIDispatch`` and ``WSGIDispatch`` are documented as top-level but aren't exposed at the top level. This is definitely an issue, I'd recommend the route of making both available top-level.
  
  --- END ISSUE ---
