Perl::...icitISA(3pm)

🎀 NAME 🎀

Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA — okay so this is the policy that says “employ use parent instead of @ISA,” and yes bestie, it’s giving class-hierarchy glow-up 💅. It lives in the User Contributed Perl Documentation zone, which is the manual name, mwah ✨.

🌸 AFFILIATION 🌸

This Policy is part of the core Perl::Critic distribution. Like, it ships with the main-character distribution itself 👑.

💖 DESCRIPTION 💖

Conway recommends employing use parent qw(Foo) instead of the usual our @ISA = qw(Foo) because the former happens at compile time and the latter at runtime. The parent pragma also automatically loads Foo for you, so you save a line of easily-forgotten code. Iconic behavior, honestly 🦋.

The original version of this policy recommended base instead of parent, which is now obsolete. So yeah, base is giving deprecated energy — not the move anymore 🙈.

✨ CONFIGURATION ✨

This Policy is not configurable except for the standard options. That’s it, that’s the config tea 🍵.
