I needed a showing of choices in the drop down list according to some criterion (object status, in my case). So, I used an array slices instead use loop.I hope that this decision will be usefull somebody. ;) 

my @list = ( [0, 'Zero'], [1, 'One'], [2, 'Two'], [3, 'Three'], 
             [4, 'Four'], [5, 'Five'], [6, 'Six'] );

SWITCH: for ($some_obj->get_status) {
    /0/ && do { @list = @list[0, 6]; last; };
    /1/ && do { @list = @list[0..2]; last; };
    /2/ && do { @list = @list[2..5]; last; };
    /3/ && do { @list = @list[3];    last; };
    /4/ && do { @list = @list[4];    last; }; 
    /5/ && do { @list = @list[2, 5]; last; };
    /6/ && do { @list = @list[6];    last; };
                @list = ();
}

$"=', ';

print "Result: status = ".$some_obj->get_status."; list=@list";
