As a programmer looking for a job? Maybe. A lot of places looking for Perl developers are looking for senior developers who understand the tooling, eco-system and a selection of "modern Perl" best practices and modules, as well as the language itself.

That's probably what you would need to learn if you wanted to be employed as a Perl developer.

Of course, if you are less experienced, you could work for a larger, modern Perl-using company where you can learn these things.
