I just want to point out, that my impression is that the maker 
scene
using all this 16 bit Arm Arduino and what ever micro controllers,
would be happy to have D as an alternative for coding in C.
So BetterC and D_16 might attract a way bigger community than many
other might think. Even if this reduced language might need to be 
named D-- :-).
