Having used both, I'd say yes. C++11 does some wonderful things, many many improvements that were a long time coming, but D put those improvements into the core language and their standard library. This makes D much more readable and hackable than C++11. Not to mention the metaprogramming support is significantly easier to use (though not more powerful, as they're both technically turing complete).
