Есть ассоциированные массивы:

Object.prototype.setHand = function(tool, worker) {	
	this.tool = tool;
	this.worker = worker;
};
obj = new Array();
obj['param1'] = new setHand(true, false);
obj['param2'] = new setHand(false, true);
obj['controller'] = new setHand(true, true);
for (element in obj) {
	trace("obj['"+element+"']:");
	trace('tool='+obj[element].tool);
	trace('worker='+obj[element].worker);
}
