Perl::Critic::Policy::Variables::ProtectPrivateVars − Prevent access to private vars in other packages.
This Policy is part of the core Perl::Critic distribution.
By convention Perl authors (like authors in many other languages) indicate private methods and variables by inserting a leading underscore before the identifier. This policy catches attempts to access private variables from outside the package itself.
This Policy is not configurable except for the standard options.
This policy is inspired by a similar test in B::Lint
