Right.  The first argument to ```.def_delegators``` is the thing being delegated to; that's why it's on its own.  As for the rest, I want them each on their own line.  But because I don't want future additions to this list to show up in Git as one deletion followed by two additions, I want a trailing comma (a coworker once called it the "Livingston-Gray comma") after the final item in the list.  At least in older versions of Ruby (dunno if newer ones extended the grammar), that means I have to use [] around the list (or {} around a hash, where I also use this trick), which in turn means I need the splat.  Make sense?  :)
