A status update:
1) I'm actively working on the array section, and will start the hash section soon, if nobody else wants it. (I posted the outline I'm working to in my last message here.)
2) I'm working on a cleanup of the whole front section, based on our all our existing content plus some I've added.
It's all in a fragmentary state right now, so please be patient with me -- work has been rather eventful the last few months. I'll post it when I have some reasonable expectation that it's remotely accurate. There's some crucial type and context related stuff that probably still has to wait for A6, however.
As I mentioned before: due to popular demand, most (if not all) pre-documentation discussion will be on p6l. This list will review documentation after it's produced, suggest text, etc., and send the final results to the design team for notes and approval.
