Are you wanting a way to provide a custom callback from your
application, or have this as a standard feature that enhances the
error return?

Either way, I would go to python-ideas with details about what you're
hoping for. It sounds like it's not going to be overly complex, so it
might end up just going straight to the tracker, but I'd start with
-ideas.
