Perl::Critic::Policy::Variables::ProhibitPerl4PackageNames - Use double colon (::) to separate package name components instead of single quotes (').
This Policy is part of the core Perl::Critic distribution.
Perl 5 kept single quotes (') as package component separators in
order to remain backward compatible with prior perls, 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
This Policy is not configurable except for the standard options.
