Even you can Open Source. :P

What I suggest–

• You can find the repository https://github.com/markstos/CGI.pm/tree/master from reading the Makefile.PL at https://metacpan.org/pod/CGI -> Browse -> ../ -> Makefile.PL
• Get or make sure you are signed-in to a github account.
• Click on "Fork" on the github page -OR- visit https://github.com/markstos/CGI.pm/blob/master/lib/CGI.pm#L7451 and click "Edit" (back at the top of the page) which forks for you and opens an editor to the right area of the file. (You may have to reload this URL depending on your browser.)
• Add in text in the paragraph along these lines-
  • Your command line will probably require you to quote your arguments. Single quote bash-style arguments are shown in the examples.
• Edit the various command lines along these lines-
  • your_script.pl 'name1=value1&name2=value2'
• "Propose file change" and add your rationale for doing so.

Update your résumé (patched CGI.pm documentation, assuming it's accepted) and watch yourself become a part of Perl history!
