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.
- compile time function execution
- modules
- no preprocessor
- memory safe arrays
- preprocessor replacement
- ranges
and so on.
Stroustoup has one vote, not everything he advocates for wins votes, including having a saner C++ (Remember the Vasa paper).

For starters, where is the paper?

Also WG14 famously killed Dennis Ritchie proposal to add fat pointers to C.
Language authors only have symbolic value once they relish control to a standards body.
