People like you make me sick, are you stupid or something? Can you understand that the person posted a sample of the code problem and not the complete application, can't you see that this is just some code to try to show the issue, but I guess not everyone is intelligent enough to read it, may be you should try to understand the problem by reading the code if you can read code at all, and not post dummy answers that is driving away the topic of the problem, the problem with some people is that they can't just see what is in front of their eyes, grow up man there might still be time for you. How can someone like you qualify to interact with people, and if you think that you are so smart and better to judge people with dummy comments like that, just don't do it, it gives a bad reputation for real programmers and Perl.
