This is a minification attempt by me. See gist history for a few in-between commits. End result is 1452 bytes by jscrush (http://www.iteral.com/jscrush/), that's where I leave it.

I've not even tested this code, I don't care myself if it doesn't even run anymore (but would be pretty sweet if it did! ;)).

The dollar signs allow you to find usages of a variable. The dollar sign itself is not used in the program, so you can remove all of them for "production" minification. As long as they're there, you can figure out where a variable is used (use case sensitive search) very easy this way.

	function J() { with (K) return caller.caller(true); }
	function K() { return J(); }
	function L() { return K(); }
	function M(stop) { if (stop) return this; return L(); }

	// without running it, what is the result of M() ?

	var call = Function.prototype.call;
	var apply = Function.prototype.apply;
	call.call = call;
	call.apply = apply;
	apply.call = call;
	apply.apply = apply;
	var hop = Object.prototype.hasOwnProperty;
	var hasOwnProperty = function(obj, prop){
	return call.call(hop, obj, prop);
	};

	// this rewrite tries to use globals for any local vars
	// you'll have the burden of extra scopes, but it beats dynamic vars (https://gist.github.com/qfox/5652201)

	// step1: change var
	var $start_foo;
	function start(x){
	$start_foo = 0;

	if (x === 1) $start_foo = 1;

	// original: https://gist.github.com/qfox/5652198
	// this would use dynamic variable access to store vars from different funcs
	// dynamic prop access could very well kill optimizations though


	// step1: change var
	var $state = {};
	function start(x){
	$state['start:foo'] = 0;

	// Rewrite to dynamic var: https://gist.github.com/qfox/5652201
	// Rewrite to global var: https://gist.github.com/qfox/5652207

	// original
	function start(x){
	var foo = 0;

	if (x === 1) foo = 1;
	else if (x === 2) foo = 2;
	else if (x === 3) foo = 3;
