Which missing features?
Say, the whole C++ ecosystem
I don't think that's fair. D interfaces with C++ better than any other language I can think of. See https://dlang.org/spec/cpp_interface.html
Delphi and .NET also come to mind, due to C++ Builder and C++/CLI respectively. :)
Or via COM, which D also supports.

I'm sorry, but even though I think D is a great language, there are plenty of usecases where D isn't a viable alternative to neither C or C++.
If D had all those missing features, or if you compared D to some other mainly-GC:ed, statically typed and compiled language, I think the syntax comparison would have been more fair.
