The easiest way to compete with Rust and cure D's GC reputation: switch to ARC.

Well not quite.

The reference count for ARC allocations would presumably exist in 
the runtime registry, not in the allocated object itself. Just 
like runtime type information does for garbage collected 
allocations.

Storing the ref count along the object would likely perform 
better, but don't think it would be done like that in D because 
the same reference types are used to deal with objects allocated 
in C.
