Perl::Critic::Policy::Modules::UserPerl::Critic::Policy::Modules::ProhibitAutomaticExportation(3)

NAME
       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.
