Hell no; why would you, if you could use D?
It links with all C libraries, and has a solid compiler and decent toolchain of its own nowadays.
All of that, but more importantly, its C/C++ done right, plus a few extra decades of accumulated wisdom in language design.
Not enough.
In order for a major shift to occur, there needs to be a killer feature.
Tapes won over vinyl because they were robust.
DVD won over tape because they didn't need to be rewinded.
USB won over DVD because it's not mechanical.
Java won over C++ because of garbage collection.
Dynamic languages won over the web because they removed the need for compilation step.
Note that in all of the above cases there are plenty of examples of incremental improvement. Zip drive did not win since it merely improved on size of disk. Blu-ray or AudioDVD did not win because they do similar.
To improve, one must change some fundamental aspect, not just iterate on existing parameters.
The killer feature of C++ over C? Namespaces, either real ones or struct/class encapsulation. And little else.
But merely fixing what is broken or improving on individual parameters simply isn't enough.
C code compiles virtually without modifications,Virtually without? Or completely without?
What about C-with-classes, which represents huge portion of production code. And if that code compiles already, why would I now start with a new language that might or might not work?
A C++ which compiles virtually all code is fine. It takes no effort, one just switches the compiler parameter in build.
D code first needs to be rewritten, build needs to be rewritten, application must then be tested and finally, in addition to all the usual bugs, a whole new class of bugs appears from "almost compatible" code.
None of this adds anything at all to final product, it takes *years* away from time that could be spent on that. Even if that problem were solved, there is still the lack of the killer feature.
without a decent, open IDEThere is no IDE for PHP. Well, there are many, but most one can hope is some trivial syntax highlighting. It certainly hasn't hindered the adoption, in many ways it made language accessible since all one needed was notepad.
