A Perl line with syntax error is still Perl.

To be frank, I don't see the point of your last line, that Q&A. It should not be too difficult for people to be nice to each other. Make pointless comment (I point to your last line) is an insult to the merit of the poster, and the community at large. I don't see this funny at all.

I read your disclaimer, but it does not entitle you to be rude, or gives you the excuse to be rude. Doesn't matter whether it is for a good purpose or a bad one, the way you expressed yourself is rude, and there is no need to put things in that way.

I point out this to you for your benefit, to be sincere. I don't jump on you because of this single incident, but you have been doing this to people from time to time.

Well, I understand how you behave yourself is really your decision.
