A few years ago I created a bare metal demo on an ARM Cortex-M4 microcontroller entirely in D. It was just a demonstration that one could do bare metal programming for microcontrollers in D without any dependencies on C or assembly. It was also a proof of some ideas I had about leveraging compile-time features of D to generate highly-optimized code (both small and fast) for these resource constrained systems. I hit a wall, however, with Issue 14758[0], and ultimately abandoned D for other alternatives.
It has a lot of potential. I always hope that someone will start a 3d Printer firmware written in D for a 32bit microcontroller.
