Yeah, you're right.

OK, that's basically right. But, What I mean `not focused` is 
that:

Rust and Nim is doing more stuff (or ecosystem) than D do.

Rust: embedded is mentioned on their Home-Page as a language 
goal. And they've done
svd2* tool to do bindings and library generation for Rust 
programming on MCU targets.

Nim: it's easier to Do configuration for toolchain in nim.cfg 
than What D do. And nim's stdlib even has support for `freertos` 
and `zephyr` for OS target.

yes, embedded is a common concept, for Big CPU or Soc like ARM 
Cortex-A or MIPS and etc With Linux-OS, D is ready for almost 
everything.

But for MCU target, D has only betterC mode, and I know there's 
lwdr, but the ecosystem is
actually a another story compared to Rust&Nim.

thanks!
