In reply to @raynei486 "I'm curious what the": I have compilers in Nim macro
for Nim -> Cuda, OpenCL, Vulkan, WebGPU as well so I have the flexibility to
create object code at build time or at runtime.

And also because you can't have per-source compiler config today (unlike
localpassc, or config.nims that allows per-source C flags)
