There are too `few newcomers` to D, and D must change.
If I can, I think `'D++'` is a good idea! Learn from a 
`successful` language!

The typical feature of `C++` is that you have it. Although I 
don't have it now, I will have it sooner or later. If D is the 
same, it may expand the community, because you can attract 
programmers from `'java, C++, py, C#` and so on.
