How do I create classes dynamically?

[Mario]

Maybe I am just too short in D, but I wanted to find out if it is 
possible to create classes dynamically. My problem is, I just 
don't know where to start reading. Maybe at mixin templates?

CreateClassWithName!("MyDynamicClassName");

should create the following class to work with dynamically:

class MyDynamicClassName {
     this() { writeln("I was not written, but still I exist!"); }
}

So that I in the end by means of

MyDynamicClassName cls = new MyDynamicClassName;

can work with it.

Normally I would think of a macro first, but as far as I 
understood D doesn't know macros (which I'm not really sad 
about), but maybe I'm just thinking too complicated yet. I would 
appreciate any hints, because as I said, I don't even know where 
to start reading.
