I've found a nice pattern of using objects and classes for configuration information, but I don't want to go all of the way to Class::DBI with them because I like the simplicity of working with flat files.
The third or fourth time I found myself writing a factory to load and to save objects to and from YAML files, I resolved someday to write a module that does that and refactor the other attempts to use the module. Today, instead of working on one of two books, cleaning my house, or doing either of the programming projects that crossed my mind, I wrote Class::StorageFactory (and Class::StorageFactory::YAML, which is what I wanted).
If it seems useful and no one objects, I'll upload it to the CPAN in a couple of days. I looked for prior art but didn't find much in a few minutes.
