The funny thing about D is that if you start writing a book about it, 
there's a high desire to change the core features and add more of them in 
the community. You can't even list all the D1 features at the moment, 
because we don't know what they are. Example:

class bar {}
class foo : private bar {}

Another one:

pragma(msg, mystruct.tupleof.stringof);

I can easily come up with 100 other such features. Some time ago I really 
wanted to write a wikibook about D. I also wanted to write a new 
compiler. It's just that D is a shitty language to work with because even 
the stable version is a moving target and/or many features are 
unspecified.
