Okay. I won't use your code. Unless your code adds something to the functionality of CGI.pm which you aren't telling us about, you are rewriting software that every default install of Perl has with it. It seems like a waste of time for me to install and test your code when I can accomplish the same thing with a lot more confidence in two lines of code using CGI.pm (albeit without the apparent subversion of the HTTP standard).

I do agree that a few silent downvotes and a polite comment or succinct criticism are better than calls for downvote stampedes. On the other hand, what if you get a job working on the website for somebigcorp.com someday? I might be using your code without even knowing it, and I'd rather a few bruises to your ego now than a compromised e-commerce site down the road. Code posters should be receptive to criticism, and those who criticize should be firm, but polite, if they expect the advice to be heeded.
