=head1 NAME

Perl::Critic::Policy::ClassHierarchies::ProhibitExplicitISA - Employ C<use parent> instead of C<@ISA>.

=head1 AFFILIATION

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

=head1 DESCRIPTION

Conway recommends employing C<use parent qw(Foo)> instead of the usual
C<our @ISA = qw(Foo)> because the former happens at compile time and
the latter at runtime.  The L<parent|parent> pragma also automatically loads
C<Foo> for you so you save a line of easily-forgotten code.

The original version of this policy recommended L<base|base> instead of
L<parent|parent>, which is now obsolete.

=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
