Unless you do really grotesque things with proxies and potentially incur
complexities at a number of other places, this doesn't work or becomes very
inefficient. Super is a property of the method in which it is being called
as much or more than it is a property of the target of the method.

On the other hand, if the mechanisms in C++ and Python are adequate then so
are the mechanisms in Lua as it exists right now.
