I am making an serious attempt to learn more Perl. So with limited time (read few weeks) at my hands, I am thinking which one are considered good skills to have. I am thinking of making myself familiar with Perldoc, Knowing basic core modules and important cpan modules, regex, perlcritic, domain specific modules, Knowing web frameworks, XML processing etc.. Technically one can say 'all of the above' plus more. I like to see your take on this issue. Thanks.
