By using the LLVM backend D could be implemented in D.
LLVM is C++ but you can output a ASM-like text file instead. I'm not sure
how much this would hurt performance, but I'm guessing it's not that much.
Also compared to what is gained it's a small price to pay.

LLVM has a bytecode VM, JIT and some pretty neat optimisation technology.

I think it could be interesting...
