I want to do something like this:

```auto
eval("var "+ class_iname +" = new"+class_name+"();");

```

But since this is not possible, how would I dynamically load different classes?

Should I use the loader class?  
This example does, but it requires pre compiling of the class in question + I am using AIR.: [http://wahlers.com.br/claus/blog/as3-loading-class-libraries-at-runtime/](http://wahlers.com.br/claus/blog/as3-loading-class-libraries-at-runtime/)

What are the alternatives?

Thanks for youe help.
