Perhaps, but somehow I doubt it'll happen. First off you would have to do it twice, once in C and once in perl. Second off Data::Dumper is optimized for speed and the overhead of sorting, especially a tied structure, could get prohibitive. OTOH Data::BFDump does sort its keys, and IIRC so does Data::Dump.

Writing a good benchmark isnt as easy as it might look.
