Description

import contextlib

@contextlib.contextmanager
def test():
    yield

with test():
    raise Exception

produces the following traceback:

Traceback (most recent call last):
  File "...\contextlib.py", line 77, in __exit__
  File "<stdin>", line 3, in test
Exception

instead of the expected:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
Exception

Research direction

Start by running the provided contextlib.contextmanager snippet and comparing IronPython's traceback with the expected output. No repository file or test is named; trace the contextlib.py and test() frames involved, and consider the work done when the exception points to the with statement rather than the context manager body.
