Js-scheme - a Scheme interpreter written in JavaScript

How is this any better than the existing n+1 scheme interpreters in javascript? Including Crockford's one:<p><a href="http://www.crockford.com/javascript/scheme.html" rel="nofollow">http://www.crockford.com/javascript/scheme.html</a>

I did (almost) this same thing 12 years ago: <a href="http://joeganley.com/code/jslisp.html" rel="nofollow">http://joeganley.com/code/jslisp.html</a> ... though his is more complete and polished than mine, and the interface is nicer in ways that were basically impossible in 1997.

"Starting in version 0.4 two extensions are packaged with the main download: a primitive API wrapper for Last.fm Web Services, and an interface to the flot JavaScript graphing library. "<p><pre><code> (load 'last.fm) (load 'flot) </code></pre> <a href="http://code.google.com/p/js-scheme/" rel="nofollow">http://code.google.com/p/js-scheme/</a>

<p><pre><code> &#62; ((lambda (f) (f f)) (lambda (f) (f f))) ;InternalError: too much recursion</code></pre>

"dude - wheres my macros?"<p>I will qualify that with: the funnest part of writing "a scheme" is implementing the macro system! Especially as you can use that to implement a lot of the r5 spec itself.

Also check out <a href="http://www.jsconf2009.com" rel="nofollow">http://www.jsconf2009.com</a> where JavaScript developers will be rallying to discuss how to use JavaScript to build cutting edge mobile, desktop, server, and web applications. If you have any interest in deep JS tech, you should be there.

Now that is one impressive hack!<p>The source to the scheme interpreter lives here:<p><a href="http://www.eriksilkensen.com/projects/js-scheme/js-scheme.js?r=50" rel="nofollow">http://www.eriksilkensen.com/projects/js-scheme/js-scheme.js...</a><p>If there ever needed to be proof that JavaScript is a real language then I think that's taken care of now.

This is absolutely kick-ass!<p>No foldl or foldr though?
