I think it would be possible to make a library that treated every  
message with more than one element as a list.  It would be a library  
of pack, unpack, prepend, append, route, etc.   But then you could use  
that library to have easier list handling, but still have backwards  
compatibilty.  Some day... maybe someone can beat me to it!
