    Um, that is my code. My cookie expired or something. Anyway, direct any ++'s here, please.

    I had similar solutions. But I improved on hole 3 to 20:
    sub hole{map/^(.*?)\1+\z/s,@_}
    and my solution for hole 5 was also 29 but somewhat different.
    sub hole{$,=pop;$,=$,<$_?$_:$,for@_;$,}
    However we can improve hole 5 to 28 taking your solution and applying my trick to it.:
    sub hole{$,=pop;$_<$,or$,=$_ for@_;$,}

    UPDATE
    Oops. My test code put hole 3 in the wrong context. My bad.
