Upgrading from legacy Lists API to REST list methods.

gistfile1.txt

# The legacy Lists API identified lists a `user` and `list_id`, which were the list
# owners screen name and the list slug, respectively.
#
# The current list methods identify a list either by numeric ID (list_id => $list_id),
# or by the owning user's screen_name and slug { owner_screen_name => $name, slug => $slug },
# or owning user's user ID as slug { owner_id => $id, slug => $slug }.
#
# So, for the most part, it's an easy transition.
#
# E.g.,  lines 251-255
            my $list_people = nt_with_retry($nt,$list_group => {
              user => $user_screen_name,
              list_id => $list_slug,
              cursor => $cursor,
            });

# become
my $list_people = nt_with_retry($nt, $list_group => {
    owner_screen_name => $user_screen_name,
    slug              => $list_slug,
    cursor            => $cursor,
});
