Well, at a high level, D does support the notion of a class.

However, D does not treat a class as an isolated conceptual unit 
(a type).

You can pretend a class is such a unit however, by isolating it 
within its own module.

So to understand D, you need to first understand the purpose of 
the module - and I still have trouble with that, since I use 
classes as the highest form of abstraction.

As for low level, which I don't do, the compiler is now written 
in D isn't it? Presumably, that involves some pretty low level 
stuff ;-)

So compare with languages that can do these two things, I would 
say.

I'm not sure that Cobol has a compiler written in Cobol??
