maybe bad thing is too strong for express my feelings. I allways saw Data::Dumper as a debugging tool, something you should keep away from your production code.
Of course, maybe good comments here from the fellow monks helped me make up my mind about this and see the module in a different way, now.
Maybe I can confine it on the dungeons of my logging system, and keep it well-feed with data to dump, and I will be happy, and the operations guys (that are mostly non-programmers) will also be able to tell something useful from the dumped data.
Thank you very much for your considerations.
