Probably not what you wanted:

>>> test()
Raises UncheckedExceptionError(exceptions.ZeroDivisionError) -> OK
Raises ZeroDivisionError -> OK
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "checked_exceptions.py", line 134, in test
    test4(3,2)
UnboundLocalError: local variable 'test4' referenced before assignment
