CGI.pm

• CGI.pm provides a ->param() method for getting the submitted web form data

• For compatibility with older packages, it will also set up an %in hash

• %in is tied to call ->param() behind the scenes

      sub FETCH {
          return $_[0] if $_[1] eq 'CGI';
          return undef unless defined $_[0]->param($_[1]);
          return join("\0",$_[0]->param($_[1]));
      }

• Other methods similarly
