Maybe have a look at Data::Locations, which can go further, and 
collect elements in all kinds of different places.   Advantages include being able to 
use ties, print, printf, etc etc.     But more particularly, it's a bit easier
to hand non-sequential data that can assembled in bits and then pulled together
in your own order at the end of processing.
