Did you actually mean to say use Exporter, or rather use Parent? Just in case it hasn't become quite clear from the other replies, there is no reason to load Exporter if all you want is inheritance (except if you want to inherit from Exporter itself, of course).
- No, I thought you had to use Exporter to use @ISA. Thanks for the correction. i went with use base as it seems like a clearer solution.
