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.
