I am assuming you are comparing C++/clang with D/ldc2, it is only
reasonable to compare C++/g++ with D/gdc. I am not sure about other
compilers.

Of course there is then the question of whether C++/clang is
better/worse than C++/g++.

Lots of fun experimentation and data analysis to be had here, if only
there were microbenchmarking frameworks for C++ as well as D ;-)
