Mark-Jason Dominus' fantastic book Higher-Order Perl is now available for free download at http://hop.perl.plover.com/book/.
This is better than the bootleg copies available from download sites in at least three ways:
- It is the complete text of the second printing, which incorporates many minor corrections; the bootleg copies are all bootlegs of the first printing.
- It does not have a nasty little grafitto advertising a vainglorious bootlegger plastered on every page.
- It was come by honestly, not stolen from the printer.
Everyone is now out of excuses for not having read it. Go read it now if you have not. You will not be sorry.
