  # These aren't 100% parallel (they're from different apps with slightly different auth rules)
  # but they're close enough to demonstrate what `with` can do, I think.

  # Version 1: using `cond`
  # Pro: very linear. just go down the list and pick the first truthy result.
  # Con: Using `cond` maybe doesn't sufficiently emphasize how important the ordering is
  #      here. If you naively swapped the order of two conditions, it could wreck the security.
  # Basically, in this version, I'm relying on the dev's caution and willingness to read
  # through my extensive comments.
