When someone mentions `users[1].address.address`, add an `if` wrapper that checks to see if `users.number() > 1`

Alternative idea: always create a loop for developers. But that might confuse some developers and is not guaranteed to be what they intended (even if it is 99% of the time).

The loop method might make sense as a default whenever it's NOT the users list.
