At this point, since you've not shown the need for inheritance implementation reuse or even interface reuse, I'd stay away from the complexity of objects. My personal rule is not to pull in OO technology in Perl until the line count of the program exceeds about 1000 lines, and using all the OO features of abstraction, inheritance, and data hiding all becomes useful. So far, all you've done is named a data structure. {grin}
