I think there were no references to ML in that part of Walter 
answer.

Currently DMD (and a bit D too) is firmly oriented toward x86, 
with a moderate orientation toward 64 bit too. Manu has asked for 
more attention toward ARM, but (as Andrei has said) maybe 
finishing const/immutable/shared is better now.
