If tracking the insert order is really important, it would probably be
better to take advantage of the Tie::IxHash module, which is available
on CPAN and many PPM repositories, including ActiveState's. It has a
number of handy features, and you can treat the hash almost like an
ordinary array. The documentation explains it quite well.
