D - more or less power than C++?

I see this often and am a bit perplexed by it. What power do you feel is 
missing?

And what about the missing power in C++ - inline assembler, nested 
functions, contract programming, unit testing, automatic documentation 
generation, static if, delegates, dynamic closures, inner classes, modules, 
garbage collection, scope guard?

What does D have to do to have more power than C++?
