I'm no embedded programmer, but a possible addition (not removal) 
might be statically proving bounds safety & reduce/avoid runtime 
bounds checking on array access; can D or Rust do that? Ada 
should be able to, with its integer range types. Actually it will 
have benefits beyond embedded as disabling bounds checking in 
release builds would no longer be justifiable.
