Rest assured we definitely do care about embedded systems programming.

It isn't about whether we want to introduce a type qualifier for low level 
programming or not. It is about what is the best solution for MMIO for low level 
programming.

Note that D already supports inp() and outp() as compiler intrinsics, adding 
peek() and poke() will complement them nicely:
