aha, that makes sense...

thanks a lot, everyone.  I've used the splat before at the end of 
parameter lists, eg

def a_method(a_thing, *args)

But i guess i didn't really properly understand what it does.  I can't 
find an explaanation in pickaxe, although it's not the simplest thing to 
look for in the index (there's no listing for 'splat' and a lot of 
listings for '*').
