`assert(0 in aa2)` actually fails too.
So it does! My bad. It makes more sense now.
When an AA is null, it must be passed by ref to modify it. Once
it is non-null, its keys and values can be modified. But even a
non-null AA cannot be reassigned by passing it without ref.
Note that an AA can be constructed using `new` before passing
by value. See:

I'll try that, thanks.
