Could you please run the most disgusting piece of data you can think of through XDumper,

Please examine the test cases in Data::BFDump and Data::Dumper. If you wish even tougher test casesd then contact me directly and I'll give you some doozies. broquaint was also helpful, ask him directly. :-)

A comment on this whole enterprise: Dumping perl data structures is a lot harder a problem than it seems on face value. Don't let that put you off though.

Good luck. :-)
