I don't use Perl much these days, but 10 years ago I would have really benefited from containerization of Perl code. That said, Perl really does become rather unmanageable for any sizable project, and was probably best used as a light weight scripting language with a great regex engine. For that limited type of use case, https://perlbrew.pl is a very handy tool.

On a semi-related note about Perl and later technologies, I was somewhat surprised Perl didn't receive more of a second wind from the early Hadoop days with 'hadoop streaming'. It seems they would have complemented each other well.

(edit: added that last paragraph)
