The only time (now) that you can take the address of function

Thinking about this, I don't know that I like the idea of
disallowing taking the address of ref.
One major usage of taking the address of ref returns is the
opIndex operator:
int *ptr = &arr[0];
Or, more generally, the front property of a range:
int *ptr = &arr.front;
What I am concerned about is that this is not going to have the
desired effect. Instead of grudgingly switching to a new style
of coding, people will simply return pointers instead of ref.
Exactly.
