That's Clojure (or—in this case—ClojureScript, which compiles down to JavaScript), which is a Lisp derivative that runs on the JVM. http://clojure.org

Looking over the commands, I thought, "Wow, this is really useful." Then the creeping dread hit. It's the kind of dread that comes along with having worked with computers for a long enough period of time: What happens when the project is eventually neglected and I am left high and dry scrambling to unlearn all of the neat shortcuts that I've come to rely on?

Then, I'll have to relearn all of the traditional methods that aren't going anywhere. Normally, I'm not a uptight about this stuff, but it's the same reason that I can't bring myself to switch from JavaScript to CoffeeScript despite the fact that I _really_ like the syntax.

It's probably TextMate's fault as well as Apple's—the latter of which seems to get a perverse kick out of jettisoning things people rely on—but, I am increasingly leery of anything that has even the most remote chance of leaving me high and dry.

The demo shows PHP and the feature list mentions "Improved Ruby," although I am not sure what that means. It's been years since I used Coda and I wasn't doing a lot of hacking back then.

Direct customers (e.g. not the Mac App Store) can upgrade for $75. Recent purchasers (via the direct channel and after April 10, 2012) can get it for free. In addition, every one can get it for $50 (half-off) for the first 24 hours, which is a great tactic if you want to elicit impulse buys through a channel that doesn't support refunds—I'm looking at you Mac App Store.

A quick and thoughtful introduction with links out to other great resources.
