True. Unfortunately, that leads to trouble with the handy "with"
construct:

    with open(path) as f:
        ...

If the open() call is guarded against exceptions (as it usually should),
one must revert to the classic syntax:

    try:
         f = open(path)
    except IOError:
         ...
    try:
         ...
    finally:
         f.close()
