I feel like some of the competitive advantage of D is falling 
away from us with some of the recent C++ developments like this 
this. Stackless resumable functions is another thing that comes 
to mind. As does the Core Guidelines Support Library/static 
analysis pair (though I suspect it'll never be quite as foolproof 
as Safe D).

We can't even do the equivalent of std::tie[1] in D as a 
workaround for tuple expansion because there are no ref typed 
Tuples (unless something changed from when I last looked).
