class private does not provide anything you can not already 
express in D.
if you don't want access to you class, put it in it's own module 
where it belongs.
but really this problem should not arise in the first place, 
because you should use interfaces anyway. a class should be an 
implementation detail.
if anything we could add the ability to declare multiple modules 
in one file, but i'm not a fan of that either.
