+If you have been led to believe that associative arrays in perl
+don't preserve order, and if you have ever craved for that feature,
+this module is for you. Simply declare a "tie" for the hash variable
+that you want to be order-preserving, and forget that limitation ever
+existed. You can do other nifty things with the tied hash object that
+you may be used to doing with arrays, like Push(), Pop() and Splice().
