You can do everything in D that you can do in C++ when it comes 
to memory management. Also a good system that tracks pointers can 
be used to turn GC allocations to malloc/free pair and some 
allocations can be turnet to stack allocations (llvm does some of 
that). Safety features can be used as performance features with 
some additional work.
