I partially agree with "Orthodox C++". Templates should be used only when needed and for turn the code simpler(not like the abomination used in most of Boost libraries).

But also, i don,t see any sane reason to reinvent the wheel and reimplement basic stuff like thread/mutex classes when the C++ version works well. Or using "NULL" instead "nullptr", or using that pre-processor macro garbage instead templates/constexpr, etc

I think some modern C++ features, that if well used, turn the code much clear and expressive.
