So as posted a few times, taking the address of the ref return value of
a property is of no value at all. If you want someone to be able to take
the address of a field, you should make it simply public (without
@property), because the @property accessor methods won't gain you
anything in this case.
@property ref T front(T[] arr) { return arr[0];}
Not being able to take an address of an array's front element is not a
viable solution. The array range's business is not to restrict access to
the first element, it's simply to conform to a certain API.
I think the point we're making here with T* vs ref T is that most good
work could and should be done with references that have provable
scoping. Needing the actual address of something should not be casual.
