Actionscript:

var cmds:Array = [["lineStyle", 0, 0xFF0000], ["drawCircle",100, 100, 50], ["drawRect", 50, 50, 100, 100]];

cmds.push(["drawCircle", 100, 100, 70]);

cmds.push(["beginFill",  0x555555]);

cmds.push(["drawRoundRect", 80, 80, 40, 40, 10, 10]);

cmds.push(["endFill"]);

 

render(cmds);

 

function render(p:Array):void {

    for (var i:int = 0; i<p.length; i++) {

        graphics[p[i][0]].apply(graphics,p[i].splice(1));

    }

}

The above creates a function called render() that takes a 2D array [...]
