I think the ship has already sailed, given the industry standards 
of SYSCL and C++ for OpenCL, and their integration into clang 
(check the CppCon talks on the same) and FPGA generation.

D can have a go at it, but only by plugging into the LLVM 
ecosystem where C++ is the name of the game, and given it is 
approaching Linux level of industry contributors it isn't going 

There was a time to try overthrow C++, that was 10 years ago, 
LLVM was hardly relevant and GPGPU computing still wasn't
