What I've done in my example is declare a variable tuple by doing Args 
args;.  So Args is a tuple of types, and args is a tuple of variables whose 
types are those of Args.  Because args is a tuple of variables, I can modify 
their values.  I guess it would be a "symbol tuple."  So if you want to get 
really technical, args is a tuple which refers to some variables -- you 
can't change the contents of args, i.e. you can't change what symbols it 
refers to, but you can change the values of those symbols.

Or something like that.  I'm not really, entirely sure :)
