For what it's worth, there is some merit in making a copy of the list, if you don't want to mutate the list that's been passed in at a later time for some reason. I'm not versed in ruby and I assume it does have a list copy operator of some sort, but there's at least merit in what you were doing, if not the mechanism. :)
