C++ is not friendly to beginners, and never will be. That is a 
well known fact.

Yes, D had the opportunity to learn from C++, yet there are more 
improvements useful for meta-programming in C++ release by 
release. So unless D starts to improve it is only a matter of 
time until that advantage is lost.

constexpr is relatively new, not a done deal, and they improve on 
it iteratively based on usage experience. The usage setting is 
core to understanding language evolution. The evolution of C++ is 
very conservative and that is intentional.
