C++ you need to write duplicate code (.h and .cpp)

C++ you need to care about header include order

C++ you need to forward declare everything you gonna use if it is 
not included before

C++ you need to waste time waiting for compile

C++ you need to fight to get proper reflection


D is much more superior to C++ in my opinion, proper package 
manager, great compile time, great module system, great interop 
with C and C++

You can use GC, you can disable it, you can use malloc, it suits 
all your need!

Can't find a lib? use a C or C++ one, that is what makes D so 
much powerfull, you don't have to give up on other ecosystem, you 
can embrace them in your project
