flash actionscript: I'm trying to create custom classes on the fly at random. for instance if i
have ball, square, triangle objects i want to spawn them at random

var newObj = new Ball or new Square, i could do a random number and then a
switch statement but i'm upwards of 20 diff classes now. Is there some nifty
way i can say var newObj = eval("new " + randomObj + ()"); random object being
a string containing the class name.

var class_str = "Square";
var c_func = eval(class_str);
