In my previous post, I talked about using Ale with vim for linting and syntax checking. Since that time, the Ale defaults for Perl have changed. Perl::Critic checks are still on by default, but you will need to enable the syntax and compile checks that are run via the perl binary itself.
The reasoning for the new default is described in the Ale docs. If you want to (re-)enable your Perl checks, you can follow the example in my dot files.
