Manual Reference Pages - PERL::CRITIC::POLICY::MODULES::PROHIBITAUTOMATICEXPORTATION (3)
Perl::Critic::Policy::Modules::ProhibitAutomaticExportation - Export symbols via "@EXPORT_OK" or "%EXPORT_TAGS" instead of "@EXPORT".
This Policy is part of the core Perl::Critic
When using Exporter, symbols placed in the @EXPORT
variable are automatically exported into the callers 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.
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
This Policy is not configurable except for the standard options.
