nope! they all look prime to me!
i like it, i'm gonna use it to explain programming loops to a mathmatician friend. i took the liberty to re-arrange a touch...

sub isPrime
{
    my $number = shift;
    my $sqrt = sqrt $number;
    my $d = 2;
    while (1)
    {
        return 0 if ( $number % $d == 0 );
        return 1 if ( $d > $sqrt );
        $d++;
    }
}
