Arguably that already describes Nvidia. Luckily for us, it has an 
intermediate layer in PTX that LLVM can target, and that's 
exactly what dcompute does. Unlike C++, D can much more easily 
statically condition on aspects of the hardware, making the 
tuning process faster to navigate the parameter configuration 
space.
