I wrote the below code

    def _decorator(func):
        def _wrapped(request, *args, **kwargs):
            set_language_changer(request, language_changer)
            return func(request, *args, **kwargs)
        _wrapped.__name__ = func.__name__
        _wrapped.__doc__ = func.__doc__
        return _wrapped
    return _decorator

What's a good function header?

Here's a good function header?
