Our latest update to Learning Perl is now available for pre-order on O'Reilly and Amazon. It should be here before OSCON 2008, but I don't know how soon before OSCON that is.
In the new edition, we've updated the text for Perl 5.10. The 5.10 features we cover are:
- using say()
- defined-or operator
- named captures in regular expressions
- smart matching
- stacked file test operators
- state variables
- given-when
Along with that, we've updated the text for the latest Perl history and happenings, and made modules a more important part of the book.
