What is D -Programming language?

Are you new to the term D programming? If you are a programmer then you may be aware of this general-purpose systems and applications programming language – D. This is a high-level language with which you can write high-performance code and interface that directly interacts with the operating system API and hardware. If you are about to write million line programs then D is ideal for that. The D programming language is easy to learn, contains many capabilities that aid the programmer, and is also well suited to aggressive compiler optimization technology.

You are wrong in 2 places
1. Support for C/C++ code
2. Multiple inheritance.
You did not show some of the shining aspects of D.
1. template meta programming
2. Modularity and the package scope
3. Compilation speed
4. Compile time function execution.
And last but not least, you did not show a single line of D code.
