in reply to "Correct" program style questions
I would personally rather not import anything in my namespace, but use the OO interface instead. This is a matter of taste, but anyway this would be "my coding style":
I know, this isn't going to work with HTML::Entities, but I made the lucky choice to use UTF-8 as encoding for our webpages, so no character escaping necessary (unless your input charset isn't UTF-8, but that's another story about Text::Iconv).
my $cgi = new CGI;
my $_name = $cgi->param('name') || '';
Otherways, I like the POSIX character classes (even more when we're talking UTF-8 and international users). I still use those old fashioned ranges like [a-zA-Z] however, 'cause we are still on 5.00_03 on our production servers blush ;-)
Do I need a Disclaimer?
