From the sort documentation: "Do not declare $a and $b as lexical variables (with my). They are package globals."

WHY? This is suddenly very frustating. Maybe some one here can help me get around this problem. I have a set of strings with a prefered sort order. So I wrote a hash associating each string to it's position in the sort order, and then a sub SortByMyOrder method to do the look ups. It gets used in lots o' places, so I moved it into a small package. But now it doesn't work any where because $a and $b are not in the right package. I could solve this with eval and caller, but I don't want to do that because qsort could potentially make lots o' calls into this method. How can I tell Perl to get the $a and $b scopes correct?
