Well, not quite, as Stefan pointed out.
Anyway, I don't see any mistery here. As pointed out by the docs,
classes, like almost anything else, are objects. A class object is
callable, and calling it creates a new instance of that class. Because
classes are just ordinary objects, you can pass them as arguments,
store them in attributes and so on.

Now 'the class' is not anything like a name or description of a class,
but the class object itself as Python sees it.
I agree that this is pretty cool stuff. But after all, it's just
the way Python is wired, which _is_ pretty cool. :)
