Eyck,
I will offer the same solution as I have to similar questions in the past. In my opinion, if you need to do things more than once in a program like sort a hash or get unique elements in an array, it is best to have a work-horse do the heavy lifting for you. While you haven't said this is the case here, it is always nice to have it in your back pocket.

Cheers - L~R
