Thanks for the suggestion: I read the item. But it's unclear whether composition is warranted in this case. I could probably get by without overlaying ->new, and in fact my modifications are small. The main reason I decided to use inheritance was to ease the implementation of Config::General over my own Local::Config. It turns out that most of my existing Config was a subset of Config::General's behavior, so I figured that by adding in a subclass those bits that weren't implemented, I could satisfy all the legacy code's Local::Config features and then start writing new code that capitalized on Config::General's features as well.

I have to admit your suggestion gives me pause, however. I'll give it another look before finalizing anything and will keep these points in mind as I work further on it.

Thanks!
