A new Student Workbook for Learning Perl

I decided to write another Perl book this week since I couldn't go to OSCON. Well, by "write", I mean update Student Workbook for Learning Perl, which I first wrote in February 2005, when Learning Perl was still in its third edition. I hadn't really thought about it too much, but this is the first Perl book I published. After awhile you lose track of the timeline, I guess.
