> Uhm. So when would I ever use this over a simple hash? Well I used it because the application I'm working on has a data model with a lot of variation (I did this instead of creating a massive class hierarchy). The accessors are the hash key scalar string. The 'equals' and 'contains' methods are delegated to the value objects when keys are "eq." (yes a wrapper object is required for the value but this could be automated.) This allows fairly complex searches of a container of objects.
This is based on an idea from a Java tutorial. I think it works better in Perl than Java because the value objects can be of arbitrary type allowing the composite hash based object to be more complex if needed.
