Here is an example
written using
Class::Factory
.
In my factory (Audio::Info),
I register all available types (look for register_factory_type, Audio::Info::Ogg and Audio::Info::MP3 for now) upon compilation,
and each type is loaded upon first use (I could've done add_factory_type instead, which would load each available type upon compilation of Audio::Info).
I hope that demonstrates it well enough.

Thanks for the examples PodMaster.
I *think* that the problem with this (for my application) is that it requires that each of the subtypes exist as seperate files? As I (belatedly) outlined elsewhere, the application requires that the packages be generated on demand (from information stored in the top level package, which itself is autogenerated from a set of large C header files). It would be possible to generate the hundreds of small .PM files directly, but the volume would make this messy and difficult to manage.

If I understand your problem, I can solve it! Of course, the same can be said for you.

This is a Straw Man, BrowserUk. At a previous job, I managed over 10,000 (initially) auto-generated classes using two scripts. It's easy, once you have the system in place. (Putting the system in place is often worth the 2-3 days it takes to get right.) Plus, I believe a responder to the initial post pointed out a CPAN solution that might get 90% of the way there ....
