No Such Function As Empty

There is no function called empty(), which could be accessed using a fully qualified name, such as ``\empty``. There is also no function that can be defined as such, since empty() is already taken.
When the code needs to pass around a ``empty function``, the best approach is to wrap a call to the ``empty()`` language construct, in a closure.
