I like the concept of C++: I provide `facilities`, you can use it 
or not.
Not that you can only do it `like this`! This is the only way.
What's more, people put forward a `reasonable` request. It has 
been implemented, but it just not been `merged`. Maybe he thinks 
D does not welcome people who are used to `C++`.
