Herbert Breunung, the tablets' author, has done considerable work since then on the overall structure of this documentation as well as describing particular details of the Perl 6 language. The tablets have reached a stage where we welcome feedback from anyone interested in reading them.
Of course, much work remains, but Herbert has finished writing the introduction and language design tablets. The variables tablet and appendices for ops, built-ins and methods, cheat sheets and summary tables, best of Perl 6 and links near completion.
Other tablets contain roughly sketched details, particularly tablets 2 to 5. So, please take a look and leave feedback below. It doesn't matter how much or how little experience you have of Perl 6: please let us know what you think so far.
