Perl::Critic::Policy::Variables::ProhibitPerl4PackageNames(3)

NAME
Perl::Critic::Policy::Variables::ProhibitPerl4PackageNames - Use double colon (::) to separate package name components instead of single quotes (').

AFFILIATION
This Policy is part of the core Perl::Critic distribution.

DESCRIPTION
Perl 5 kept single quotes ("'") as package component separators in order to remain backward compatible with prior "perl"s, but advocated using double colon ("::") instead. In the more than a decade since Perl 5, double colons have been overwhelmingly adopted and most people are not even aware that the single quote can be used in this manner. So, unless you're trying to obfuscate your code, don't use them.

    package Foo::Bar::Baz;    #ok
    package Foo'Bar'Baz;      #not ok

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