Has anyone used D with Nvidia's Cuda?

Oh, I understand that keeping things up to date is always a problem with every 
third party tool. On the plus side, however, Nvidia seems very good with 
backwards compatiblity, meaning that when the D bindings get out of date, they 
will still work. They just won't work with new features.

Of course. But having a couple examples to show it really does work will go a 
long way. I am not suggesting making any attempt to duplicate Nvidia's 
documentation in D.

If that's the state of things, I'd be happy to take them over and put them in 
Deimos.

That does work for someone who really wants to use CUDA, but not much for 
someone who is evaluating using D and wants to use the GPU with CUDA.
