I don't really see why you're thinking of them, but if you look at how they do it, you'll see that they use some run time magic to work as if they were written as conventional functions. This invariably involves some accessory data, like printf's format string, that in effect tells the function its parameter implementation at run time - including number of parameters, since you can't tell even that from standard args data as far as I know. What this proves is that you can implement an argument list at run time, but it by no means changes the nature of the argument list as a sequence.
