class CM:

    def __init__(self):
        pass

    def __enter__(self):
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        raise RuntimeError()

if __name__ == '__main__':
    with CM() as cm:
        print('Hello')

$ python3 cm.py 
Hello
Traceback (most recent call last):
  File "cm.py", line 14, in <module>
    print('Hello')  # <--
  File "cm.py", line 10, in __exit__
    raise RuntimeError()
RuntimeError

Is it correct that print presents in backtrace? Well it's the last line but...

Thanks.
