25463	RFE: support chained exceptions in DEBUG traceback view under Python 3.5+	ncoghlan		"I'm currently attempting to debug what appears to be an error handling bug in Django REST Framework: https://github.com/tomchristie/django-rest-framework/issues/3446

However, the error I *really* want to be investigating is the original one, rather than the secondary failure in the DRF exception handling.

Python 3 captures this information in the `__context__` (or `__cause__`) attribute on the exception object, as described in https://www.python.org/dev/peps/pep-3134/

It would be handy if the DEBUG view could be updated to display that information when it was available (although I have no idea how difficult such a change would be)"	New feature	closed	Error reporting	1.8	Normal	duplicate			Unreviewed	0	0	0	0	0	1
