I'm using D (gdc) for all my personnal and professional projects. At the moment, the only reason I have to sometimes regret C++ is Emscripten, which only accepts C and C++ as input (although it might change one day thanks to ldc compiler).

Everything else works: calling C functions, ctags, syntax highlighting, automatic make dependency generation, integration in Visual Studio, step by step debugging, profiling (oprofile), valgrind, etc. As a bonus, D makes a fantastic "scripting" language (= no explicit compilation step): at work, we're progressively replacing all of our bash scripts with D scripts.
