Perl 7 is coming. In short, it’s v5.32 with different defaults. No new features, no fewer features. Different settings. Sawyer X envisions a release within the next year, maybe sooner.
I’ve made an announcement and written a provisional book on what you need to do. Many of the features and tips I’ve already written about here will help you prepare for Perl 7.
Perl 5.32 was just released, so your first step is to get your code working under that version. After that you should be in pretty good shape.
