Perl::Critic::Policy::Modules::ProhibitAutomaticExportation - Export symbols via "@EXPORT_OK" or "%EXPORT_TAGS" instead of "@EXPORT". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
When using Exporter, symbols placed in the @EXPORT variable are automatically exported into the caller's namespace. Although convenient, this practice is not polite, and may cause serious problems if the caller declares the same symbols. The best practice is to place your symbols in @EXPORT_OK or %EXPORT_TAGS and let the caller choose exactly which symbols to export. package Foo; use base qw(Exporter); 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 CONFIGURATION
This Policy is not configurable except for the standard options. AUTHOR
