As discussed on Python-Ideas, there's some interest in a context manager that can convert an exception from one type to another (similarly to the way PEP 479 has StopIteration converted to RuntimeError.

See the thread starting here:
https://mail.python.org/pipermail/python-ideas/2017-June/046109.html

and particularly Nick's comment here:

I've written a recipe on ActiveState:

https://code.activestate.com/recipes/580808-guard-against-an-exception-in-the-wrong-place/

which acts as both a context manager and function decorator. That can be used as proof-of-concept or as a basis for a PR.
