Perl::Critic::Policy::Modules::ProhibitAutomaticExportatUser3Contributed Perl DocuPerl::Critic::Policy::Modules::ProhibitAutomaticExportation(3pm)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.

Perl::Critic::Policy::Modules::RequireEndWithOne - End each module with an explicitly "1;" instead of some funky expression.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
All files included via "use" or "require" must end with a true value to indicate to the caller that the include was successful. The
standard practice is to conclude your .pm files with "1;", but some authors like to get clever and return some other true value like
"return "Club sandwich";". We cannot tolerate such frivolity! OK, we can, but we don't recommend it since it confuses the newcomers.
CONFIGURATION
This Policy is not configurable except for the standard options.

Hi,
Can someone please clarify how we are able to use both IO and GLOB symbols of a package variable interchangeably?
Please consider the following code:

my $glob_var = *main::FH{GLOB};
my $io_var = *main::FH{IO};
