To see if 2 data structures are different, and where they begin to
differ, use the "is_deeply" function from the Test::More module. For
more complete/complex comparisons, use one of:
http://search.cpan.org/dist/Test-Differences/
http://search.cpan.org/dist/Test-Deep/

Of course you could also try to roll-your-own by using Data::Dumper
and making sure array keys are sorted in the output (e.g. use
"$Data::Dumper::Sortkeys = 1") for each structure, but I think for 90%
of the cases one of the above modules should serve you well enough.
