I wanted to write the card game mentioned here. Being too lazy to install the Arthmetic:: Numerical::Shuffle module I decided to make to improvise. My deck would be(until I got Shuffle.pm) cards numbered 1 through 100. In order to "shuffle" the deck I used this: 
foreach(1..100){
    do{$i = rand(99)}while exists($seen{$i});
    $seen{$i} = 1;
    $DECK[$i] = $1;
}

But now I'm getting a bunch of empty elements in $DECK. Why?
