D is the result of lack of interest by the C++ committee, and I had little interest in spending literally years trying to get useful things adopted into C++.

Ironically, over the years, C++ has adopted many features popularized by D.

(like contracts!)

C++ should adopt a few more D features, like https://www.digitalmars.com/articles/C-biggest-mistake.html, compile time expression evaluation (C++ did it wrong), forward references, and modules that work. C++ should also deprecate the preprocessor, a stone-age kludge that has long been obsolete.

I think you are leaving out the fact that your comment applies to the post-C++98/pre-C++11 hiatus.

Once C++11 was released, the truth of the matter is that whatever steam D managed to build up, it fizzed out.

I'm also not sure if it's accurate to frame the problem with C++0x as picking up features from D. As I recall, D's selling point was that it was scrambling to provide the features covered by C++0x but users weren't forced to wait for a standard to be published to be able to use them. Once they could, there was no longer any compelling reason to bother with D anymore.
