A few years back, we really tried to find a way to do it that was memory safe. 
We failed. Timon presented us with a use-after-free case that we couldn't 
resolve. Re-orienting D around a memory-unsafe construct is not the future for D.

There's also the problem that the decrement has to be in a finally block, 
because of exceptions, which makes things bloated and slow.

P.S. A borrow checker resolves the use-after-free case, but RC isn't needed if 
one is using a borrow checker.
