I'm excitedly looking forward to Kernighan's new book. But more than that, I'm very happy that the "Go rocket" has now definitively cleared the launchpad – and predictably, heads are exploding all over that great bastion of PL hipsterdom, Hacker News.
As an aside, the Reddit community seems way more mature and not react predictably all the time. See this thread, which is really a humorous meta-comment on all such discussions:
— No generics means reading the code is easier, somehow!
Anyway, all I know so far is the Table of Contents, but stay tuned for more!
