Perl::Critic::PoPerl::Critic::Policy::Modules::ProhibitAutomaticExportation(3)NAMEPerl::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.
