Andreas Stührk added the comment:
It was reported as bug to a project that uses the traceback module
(https://github.com/bpython/bpython/issues/651). Parsley
(https://pypi.python.org/pypi/Parsley) is at least one library that uses
unhashable exceptions, although I guess it's by accident
New submission from Andreas Stührk:
The traceback module tries to handle loops caused by an exception's __cause__
or __context__ attributes when printing tracebacks. To do so, it adds already
seen exceptions to a set. Unfortunately, it doesn't handle unhashable
exceptions:

As the test demonstrates, it's still possible to trigger a dynamic lookup
without the patch, hence I think this is still needed and valid, yes.
I updated the patch to make it reflect the latest committed changes.
