I'm excited to see a P6 book, but don't know why O'Reilly isn't funding it unless Brian gets to keep most of the $. Some things I'm concerned about are the crazy short length (350 for a language this big), what will be included, and the fact that it sounds like he is still in the exploratory phase.
I understand why O'Reilly might do this- it mitigates risk and may help you judge whether this is a title to push or not.<p>But it does make one wonder if they are superfluous.<p>Not: is an editor or typesetter superfluous. You can contract that pipeline.
That's great news! Perl6 is a powerful language, unfortunately, it lacks a book which is a studding method many needs to pick up a new language. I will back it up!
O'Reilly is now participating in Kickstarters for books they plan to publish? Wow. Things must have gotten really tough for them.<p>And I'm not saying this to gloat, in case anyone interprets it that way.
