Perl::Critic::PoPerl::UseriContributedMPerleDocumentationtomaticExportation(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 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

CONFIGURATION
       This Policy is not configurable except for the standard options.
