It does work. Variant number 4 :). Guess I was array fixated by the first two variants.

Perl is Huffman encoded by design.

    If I understand everything correctly then I don't think this is a fourth variant: 
     \@$choices

    compared to 
     $choices

    I think you need to look up array refs and pay particular attention to referencing and dereferencing. In both cases you have an array ref, however in the first you deref it only to then make it a reference again. The second doesn't do this unneccessary merry go round.

    HTH.
