37    # (based on a few experiments)
38    #
39    #   1. The person who wrote the tweet you are replying to is added.
40    #      This is the only time when your own name can show up in an
41    #      at-reply string.
42    #   2. Next, Twitter goes through the Tweet front to back, adding
43    #      mentioned usernames that have not already been added to the
44    #      string.
45    #
46    # In degenerate cases, the at-reply string might be longer than
47    # the max Tweet size; Twitter doesn't care.
