Perl::...rtation(3pm)

✨ NAME ✨

okay so bestie, welcome to Perl::...rtation(3pm) — that's the manual name right there — from the User Contributed Perl Documentation crew. The full policy name is Perl::Critic::Policy::Modules::ProhibitAutomaticExportation, and its whole thing is: export symbols via @EXPORT_OK or %EXPORT_TAGS instead of @EXPORT. periodt. 💅

💅 DESCRIPTION 💅

So when you're using Exporter, any symbols you put in the @EXPORT variable get automatically exported into the caller's namespace. Convenient? sure. Polite? not it. It may cause serious problems if the caller declares the same symbols. fr fr, that's a whole mess.

The best practice is to place your symbols in @EXPORT_OK or %EXPORT_TAGS and let the caller choose exactly which symbols to export. slay. 🫶

package Foo;

use Exporter 'import';
our @EXPORT      = qw(foo $bar @baz);                  # not ok
our @EXPORT_OK   = qw(foo $bar @baz);                  # ok
our %EXPORT_TAGS = ( all => [ qw(foo $bar @baz) ] );   # ok
