As soon as I got the release email I came here to check if this had been posted to HN; it’s an incredible piece of work, and I highly recommend it. It sweeps away much of the mystery behind programming language internals in a clear, easy-to-follow, humorous way.

I worked through the first half of the online book recently, and am excited to buy the print version and work through the rest of it. I can’t get over dead trees, and as fun as it was using the free online version (thanks munificent!), the paperback version will be even better.
