Here's a good function header given the following:
I wrote the below code

    @functools.wraps(fn)
    def _core(*args, **kws):
        config.COMPATIBILITY_MODE = True
        try:
            fn(*args, **kws)
        finally:
            config.COMPATIBILITY_MODE = False
    return _core

What's a good function header?
