Actually, File::Spec is one of the worst examples in the Perl distro, because it's all about class methods, and no instances, and alters global behavior with global switches instead of carrying differing states around in instance variables.

For distro-only examples, see the IO::File hierarchy. A little messy, but the inheritance, class, instance, and constructor methods are all pretty interesting and a good use of inheritance (and even dare I say "multiple inheritance").
