Perl 6 Essentials, which is planned to re-issued several times during Perl 6 development, aims to keep working Perl users about the decision architecture, additional features, changes in syntax, and community development that occurred. The idea is that if you follow the series 6 Essentials Perl, you'll be ready to go when it appeared the final release - if you are not inspired to join the first development effort. A software developer tired, after seeing too many substantial "face" books rushed to press just so that they can only books available on their topic for a while, perhaps suspicious of this book. The author clearly explains what's new (so far) in Perl 6, and did an excellent job explaining the architecture of new Parrot virtual machine. The authors have a good sense of what Perl developers want to know about their working future environment, and satisfy the demanding Wall. - David Topics covered: The state of Perl 6 development effort through Apocalypse 6 (milestones of development) and the Parrot virtual machine through version 0.0.10.
