=head1 NAME

Perl::Critic::Policy::Variables::ProtectPrivateVars - Prevent access to private vars in other packages.


=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic|Perl::Critic>
distribution.


=head1 DESCRIPTION

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.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.


=head1 HISTORY

This policy is inspired by a similar test in L<B::Lint|B::Lint>


=head1 SEE ALSO

L<Perl::Critic::Policy::Subroutines::ProtectPrivateSubs|Perl::Critic::Policy::Subroutines::ProtectPrivateSubs>
