I found this [1] to be an interesting overview of how the Pnuts
programming language [2] handles classes (a new feature for the
language). We haven't heard from the Pnuts developers yet--I hope they
get a chance to tell us about the language sometime.
There's an old review of Pnuts by Steve Yegge, when he was trying out
several JVM languages for a "shootout". The site isn't available
anymore, but archive.org has the link [3] (slow, at least for me). I
believe he was using a slightly older version of Pnuts.
