Yes indeed, null initial value is reasonable. My suggestion does
not affect that rationale, but is only based on my observation
that if someone want to `refer` to an AA, he is more likely to
fill it very soon, and he really mean to refer to it. These are
similar concerns:
- create a null AA,
ed AA.
Actually, I think ANY structs that mimics a reference behavior
should add this rule to really look like a reference.
