i need to create a few lists of unique random numbers 

## set %availableNumbers
%availableNumbers =();
for ($i)5{) { $availableNumbers{$i} = 1; }

## create lists in a foreach loop
%lists = ();
@listIDs = (1,2,3,4,5,6,7,8,9,10);
$itemsPerList = 10;
foreach $listID (@listIDs) {
  my %myAvailableNumbers = %availableNumbers;
  for ($i=1;$i<=$itemsPerList;$i++){
    @myAvailableNumbers = keys %myAvailableNumbers;
    my $number = $myAvailableNumbers[rand($#myAvailableNumbers)];
    push @{$lists{$listID}}, $number;
    delete $myAvailableNumbers{$number};
  }
}

so that works

i just intensely dislike the:
@myAvailableNumbers = keys %myAvailableNumbers; line anyone know how i can rewrite that section to get rid of it?
