List shortage of Perl
I list shortage of Perl.
Object-Oriented feature in coreFor a long time, Perl don't support clean Object-Oriented feature in core. Ruby and Python can write OO programing clean, but Perl can't. This will be resolved by adding mop to core in the five years.
Web applicationPerl don't have famouse Web application. For example, PHP have Word Press, phpMyAdmin, Python have trac, Ruby have redmine, GitLab, but Perl don't have. I think we need to see web world.
Web service startupPeople think Perl is old language. If people contine to think this, People tend not to use Perl in web service startup. Now Perl have Mojolicious, Web startup is easy and clean. Perl disadvantage is none compare with Ruby on Rails. We can recommend Web service startup with Perl.
Statisticsage is attending to big data and staticstics. In this area, most people maybe select R language and Python numpy and scipy. Perl have PDL, but I think most people maybe select R langauge and Python numpy and scipy. These are more clean and simple than PDL and Perl. People tend to select clean and simple interface. I want clean staticstics library.
Perl comunity tend to attend to CPAN and Perl language itself,
but I think we need to see the outer world of Perl itself and CPAN.
