The Perl 6 book at Wikibooks has begun. This morning I threw down drafts discussing some basic ideas about variables, sigils, and contexts. As much as I wish I could have run Synopses 2 through some kind of POD2Wikitext translator and just posted that.
I was realizing as I read through S02 this morning that it's really quite a complex document and is pretty inaccessible to people who aren't familiar already with Perl and programming ideas in general.
The book however really needs to be accessible to all audiences, including people who maybe haven't programmed Perl 5 before, or people who haven't programmed in a dynamic language before, or even people who have never programmed at all. We have to start off with baby steps introducing little terms and little ideas first and then slowly building up to the bigger ideas.
Writing this book is not going to be a fast process, but I have a handful of pages drafted up so far and would love to get some feedback on them.
