And, no, I want no mutable references such as C++.

Walter has been adamantly against having ref variables like C++ has. They're a potential @safety issue and add a fair bit of complication to the language. I doubt that suggesting that we have them as const-only would change his mind any - especially since that addresses none of the @safety
issues.

If I can't mutate them, where are the @safety issues?
