In D I've the added complexity in trying to use the game engine 
(cocos2dx, unreal, cryengine) C++ libraries from D.

So that's not worth the effort, if I can't use D's powerful 
standard library as usual.

I don't like the idea that any hidden object allocation or string 
concatenation can trigger a GC for an undefined amount of time.

In C++ you also have plenty of objects constructors/destructors 
called everywhere in your back, but none of them will ever 
trigger a GC...
