	Please note, this class is not at all more safe than to use the
	va_list macros directly, it's just a slightly more convenient way
	to first start and then subsequently end a va_list.

	And please do keep in mind the comment above, just as with va_arg,
	the only possible error indication you'd ever get from this class 
	is a crash because of memory access violation (unless you're using
	clr:pure).
