The following code looks pretty assembly-like to me ;) This is my state-of-the-art pattern matcher for Clojure working w/ ClojureScript.

While this may look scary the pattern match compiler now emits precise errors (not shown here).

Also I mentioned to Brendan Eich that I created an 8 line ClojureScript macro to marry closures and prototypes.

You would not write any of this stuff by hand.

ClojureScript lets you fully leverage the promise of JavaScript. I haven't seen anything else that comes even close.

It also looks like the kind of code one would generate when C is the target language.

Sure before Google Closure takes an optimization pass at it. Anyways, I don't really think it's a point worth debating to death - I defer to Erik Meijer.

Your first example has massive code duplication. If you did that in idiomatic JavaScript, it would be smaller, faster and debuggable.
