Perl legend chromatic has written Modern Perl: the book. (See also the excellent Modern Perl Books companion website.)
The book is available in paper form for purchase, and for free download in PDF and other sundry formats from the publisher's site. And while the book's source has scripts and instructions for building an HTML version, I couldn't find one hosted anywhere yet. So here it is.
(I threw together this index page in about 10 minutes. Please don't blame chromatic for it.)
If you find this book useful, consider donating to chromatic (the donation link is at the bottom of the page).
This is version 09e988f80aec4e679a6b9c8821528d44d191e6ac. I'll try to update periodically if there's interest.
