I use D in an automotive environment (it controls parts of the 
powertrain, so yeah there are cars running around on D) on 
various types of ARM Cortex M CPUs, I think this will be the best 
way to extend D to those platforms.

The existing runtime is PC-oriented. Embedded stuff doesn't need 
a GC or some of the more advanced features, but having things 
like classes, interfaces, dynamic arrays would make the 
development workload a lot easier.

A lot of embedded stuff is done with RTOSs now that provide 
memory management and threading support, so having a flexible 
lightweight runtime with a generic backend (mem allocation, 
threads) that I can hook to the RTOS' libraries would be great.
