I'm not rating the module as I am the author of Data::TreeDumper and thus may be too partial.
Does very little that Data::TreeDumper doesn't and doesn't lots of what it does.
The integration of a table for the dump of a 'Lists-of-Lists' is an interesting idea as is the 'Method introspection for objects'. But even those are not enough for the creation of a module which copies an existing one. I would have appreciated patches or extra modules instead.
In any case, TIMTOWTDI and I hope this module will find many users.
