How about this?

final class Boxed(T) {

        this(T val) { payload = val; }
}

Boxed!int i = new Boxed!int(123);
int j = i; // hooray, implicit unboxing!
i = 321; // even this works

Pretty neat solution, you need an extra type but that's not much. 
If alias this would be removed in D, would tricks like these 
suddenly become impossible?
